hi,
i want to encode a string that users enter with mysql password function. but
sometimes this code works sometimes don't. mysql warns me:
Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result
resource in ........
the code is:
$result=mysql_query("select password(".$_POST['password'].")");
while ($p = mysql_fetch_array($result, MYSQL_ASSOC)):
$pswrd=$p['password('.$_POST['password'].')'];
endwhile;

Monil,
First, from the perspective of the Web server, there is only one
browser. Also, there is no way to know when a user closes a browser.
So, your problem just sounds like PHP is *maintaining* the session,
which is exactly what it is supposed to do. :-) It is your job to
maintain the data associated with a particular session, and there are
functions to help you destroy data in a session, or you can simply
reinitialize all of your session variables when the user first selects
an option from the menu.
Happy hacking.

i wish to POST submit to a login form on another server and then after that
POST some more information on the resulting page.
the thing is, after the first login, the website sends me a cookie. it
probably holds the session id and or authentication information. how will
can i relay this back to the page so i can view the resulting page without
being kicked out because of no cookie??
ive already used curl and am able to post things to scripts. but this cookie
problem i dont know how to get around.
any idea?
cheers

The example below is correct, however in many cases you can avoid the
anonymous search. If say for all users you have entries with dn's like
uid=dj, o=users, dc=mycompany, dc=com
you can just do
$dn = "uid=$inp_uid, o=users, dc=mycompany, dc=com";
$ds = ldap_connect("ldap.someserver.com");
$r = ldap_bind($ds, $dn, $inp_passwd);
and check whether $r is true. Someone reported that there is some
implementation where this is falsely true for empty password, so
prior to this I would chech that the password string is non-empty,
just to be sure.

Hi,
I'm using a Win2k with php4.1 and I'd like to make some thumbnails from
pictures on my disk.
I've gotten the impression that it's possible, but I havent' found out
just how.
I've stumbled across the ImageCopyResized function but it requires a
imagehandle(?) to the file copied from. How do I get that? Is it the
right way to do this?
I guess I could use some picture manipulating program to do this, but
doing it the PHP way is nicer :)
TIA

From a php script yes, but not by PHP, because PHP runs on the server,
not the browser. If you use JavaScript you can close it with window.close()

I can't imagine how anyone could thing this is a good idea!
What's next? Change my browser preferences without asking me? Move some
files around on my hard drive?
FWIW, PHP is a SERVER SIDE language. It doesn't interact with the
browser... by the time your browser recieves a page, it's just plain HTML,
which can be seen with view > source.
To do something as horrid as closing a browser, it would have to be done
with something like JavaScript on the browser (client-side). For example,
self.close() (forget exact syntax) in JavaScript may do what you want.
I still can't see an occasion where you'd want this... at least not on a
consumer site.

I have a few application design questions that I was hoping someone
might have some thoughts on. I'll warn you in advance that this post
is kinda long winded. I'll try my best not to use two many trendy
buzzwords, but I may not be able to avoid it. :-)
I work for a real-estate company and one of the functions of our
website is to (obviously) allow customers to search our listings
database. I currently have a fairly straightforward set of PHP pages
that accepts search criteria, constructs SQL queries, and then
displays the listing data. For quite some time this was more than
sufficient for our needs.
Recently we added a new application to what we provide that allows
customers to sign up to receive new listing notifications based on a
certain set of search criteria. I was charged with the responsibility
of creating this application. I decided (for various reasons) to
implement this application in Perl.
As I was putting the Perl script together I realized that I was going
to have to duplicate all of the business logic that existed in my PHP
pages to build the SQL queries and display the results. For example,
different listings have different rules for display. Some bits of
information cannot be legally displayed based on the location the
listing is in. All of this business logic was wrapped up tightly
inside my PHP pages, and I realized I was going to have to implement
it again in my Perl script. Worse yet, I realized that if any of this
business logic changes (which it often does), I was going to have to
remember to change it in TWO places. Up until this point there was
only the website, but now that I had two completely seperate
applications that I have to maintain whenever anything changes.
I realized at this point that I would be really nice if the business
logic that determines how to construct the queries and which bits of
data to display were completely seperated from the presentation logic
that existed in my PHP pages. If I had some sort of component that
merely accepted search parameters and returned data then I could
access this component from both the PHP page and the Perl script. If
the business logic changed later I could simply update the component
and I (theoretically speaking) wouldn't have to touch the PHP page or
the Perl script.
I've been doing research into this kind of application design. From
my limited and inexperienced perspective, it does appear that
Microsoft does offer some advantages in this area. But COM is not an
option for me, for several reasons, not the least of which is the fact
that our servers run Linux and I cannot access PHP's COM functions.
I have considered setting up a PHP page that runs on a seperate port.
This page would accept search criteria via a query string, and then
return listing data in XML format. Then on the PHP presentation side
(or my Perl script), I would parse the XML and either display it
manually, or use XSLT.
I don't have a lot of experience with this, however. It seems that
XML support in PHP is still in a state of infancy. I'm aware of
Sablotron, and I have successfully compiled PHP with Sablotron
support. But I've read articles that the SAX implementation that PHP
employs is inferior that the DOM model. I've also read that the PHP
developers are working on improving the support for XML and XSLT by
using libxslt instead of Sablotron in later versions. After reading
all of this, it seems like the best thing to do is to wait a bit until
XML support in PHP solidifies a little more.
Also, I am concerned that the overhead of connecting via TCP (even if
on the same physical web server), having a page generate XML,
receiving the response, and then having to parse it back out again,
might impact peformance too severely. On our website, the most
popular thing is searching listings. If I drastically reduce
responsiveness by adding all of this overhead, then I've made things
easier for programmers, at the expense of the end user.
Another technology I was toying around with is Java servlets and Java
Beans. I'm a complete newbie when it comes to this stuff too, but
from what I've read it seems that Java Beans are designed to wrap up
business logic in reusable components. Money is an issue, however, so
if I implemented anything in Java I would have to use Apache's Tomcat,
and not one of the commercial Java platforms. I realize this is
wildly off-topic for this list, but if anyone here has any experience
with Tomcat I'd appreciate any advice (off-list if necessary) as to
whether I'm barking up the wrong tree or not. :-)
Thanks in advance to any advice anyone can give...

Yes, this is exactly what you should do. Design (redesign?) your Web
application with a more modular approach. Make your business logic in
separate modules. There is no need to use a different language for this,
however, especially since your business logic is probably simple
decision making based on information from a database.
>I have considered setting up a PHP page that runs on a seperate port.

Don't forget that PHP has a CLI (command line interface). For example,
create a script like this:
#! /usr/bin/php -q
<?
echo "PHP has a command line interface!";
?>
Make it executable and execute it, just like a Perl script.
Basically, it's really easy to create multiple interfaces to the same
business logic. Don't try to make things more complicated than
necessary, and since there is no need to use multiple languages in your
implementation, that is a complexity worth avoiding.
If your Web application utilizes a modular design, then all your PHP
script has to do is include the appropriate business logic from your Web
application. Then, you can set it up with cron or whatever to decide who
needs to be emailed what.
Happy hacking.

I began programming in Perl back in 1995. Took up mod_perl (the only
way to seriously use Perl btw on web apps) but as I work primarily on
virtual servers mod_perl was just too sophisticated for most
environments, so I settled for just Apache::Registry which would also
run as plain cgi. Well ... I've finally found a nice framework using
PHP (using smarty.php.net) with Pear and then private classes for the
App at hand. Works like a charm. I'm a fan of Perl but you can't beat
PHP for ease of deployment and PHP does everying Perl does (all that I
need) (although not all that mod_perl allows but then those conditions
are pretty rare, for instance, like taking command at any of the apache
request phases, especially good for custom auth stuff).

Oh yeah, avoid that at all costs. Sounds like something like SOAP etc.
could have been an answer, but then it depends on how you write your
apps.
I write both Perl and PHP to manipulate data. Every function has input
and output and those are just arrays. I ran into a similar problem with
NUKE. My customer wanted me to allow a user to join via a multi-
newsletter module I was writing. Well I got it to work but it was not
as easy as it should have been imho. I should have been able to call
CreateNewUser and pass it the require input and gotten back a user id
and then I could have called soemthing like GetUser and pass it a user
id and get back an associative array (my pref) of that user. It was not
like that, not at all, or I missed it. It seemed that the creation of a
new user was tightly *coupled* with an html signup process.

Ummm .... like the other guy said, why bother? You can do that. Of
course. But what are you doing in Perl that you cannot do in PHP? Maybe
a cron script? I've not written any cron stuff in PHP and I'm not
calling lynx to do it as I've seen advertised :( ...

SOAP, XML-RPC
http://php.weblogs.com/xml-rpc
I just did a search on Google. I have not written anything along these
lines but given XML you could write your own but I'd always go the
public route if I were to do this.
I'm reading an interesting book called "Software Architect Bootcamp"
where components is the big word. It's interesting. I'm not sure if
I've got a full grasp but it defintiely seems to have an emphasis on
decoupling (something going back to I read about in McConnell who is
very good). But how to implement? In the book I'm guilty of what he
calls the Stovepipe System :( but I'm working on it.

I don't know about that. Works well for me. I take an Amazaon XML feed
and run it through my smarty templates with no problem here:
http://www.readbrazil.com/books/amazon.php?mode=books
please note that above site has been more of a php playground than
anything else.
No need to go the XSLT route although that is interesting. I use
Template::Toolkit in Perl and have templates in html, xml, or plain
text.

I really don't now enough about this. Seem strong to me but I have'nt
done much.

I think you can do all of this in PHP. But I don't think there is any
easy answer. I have a website I work on now and then (using geeklog)
http://www.smartarchitectures.com/ and I plan it to be about just what
you are talking about. I don't think your question is really language
specific. A lot of these books and what not are big on the strategic
but then they leave the details out of the picture.
It sounds like to me you are looking for a framework. This what I
looked for in PHP and I've got one now that is equal or better to my
Perl framework. I use the same pattern I do in Perl. Isolate data
manipulation, functions are the sort of "programming by contract" where
functions expect input and return output. It gets messy when I have to
handle errors ... I'm trying to componentize my stuff to decouple it
all ...

Point well taken. However, allow me to explain some things that I
left out of my original post:
I decided to go with Perl for a few different reasons. First of all,
I wanted to get more comfortable working with Perl, mainly so I could
get exposed to languages other than PHP. I had used Perl in the past,
but only for small tasks. I saw this project as an opportunity to
pick up some useful Perl experience.
Another reason I went with Perl is because IMHO some of the tasks I
needed to accomplish are just easier done in Perl. Part of the
functionality of my script is to parse incoming email and take
different actions based on it's content. My script responds to
certain embedded commands (subscription confirmations, unsubscribe
requests, requests for automated help, etc.). It also forwards
unknown commands to one set of addresses, while forwarding DSN's to
another set. This means accepting the mail on STDIN and doing a lot
of regex parsing. I know that this is more than possible in PHP, but
Perl just seems better suited to this type of task IMHO.
In retrospect it probably would have been better for me to implement
everything in PHP, from a modularization point of view. I could have,
like you suggested, put all of my business logic in say a class, and
included that class from both my webpage and my mail script. But that
would lock me in to using PHP for everything that needed access to
that business logic, so I'm still not sure that is the best
solution...
Thanks for the response...

Well, that is basically my question. I considered both SOAP and
XML-RPC (which you mention later) but I wasn't sure what the impact on
performance would be. I am basically looking for anecdotal evidence
from people who have implemented this sort of thing before...

I answered him in a seperate post, but I'll repeat here: I'm familiar
with writing standalone scripts in PHP. I used Perl because for this
particular task it seemed better suited, and I wanted to get some more
Perl experience. In retrospect it was probably not the wisest
decision, and I probably have made things more complicated than
necessary...

That was just the impression that I picked up from my admittedly
limited research I did on XML support in PHP. I was focusing mainly
on XSL transformations though.
Do you mind if I ask how exactly you are parsing the XML in your PHP
pages? It seems to me that there are a few different options
available on www.php.net. There is the --with-xml option that uses
expat, and then the DOM XML extension that is marked experimental.
I'm a real newbie when it comes to XML, but the DOM functions look a
little more attractive to me...

Thanks for your response, you've given me some nice food for thought.
I've heard of Smarty several times before but never looked into it. I
definitely will take a look at it now...

I was just looking at my software architect book ... not half-way
through yet. Good book. CORBA is what is mentioned know, a bit
different than SOAP but I don't know enough of either yet to say for
sure.

Personally, I think you were correct. I cannt imagine just doing
everything with one tool. But how to write PHP and your Perl so they
can talk to each other. Dunno. IDL, CORBA .... but as you say, it sure
would be good to hear from someone who's been here already.

Yes, I avoid XSL with the SABOLOTRON (or whatever it is) cus it's not
in most virtual environments and that's a reason to use PHP over Perl,
the ease of deployment. If I have my own box, heck, mod_perl is strong.
Anyhow, I'm a lazy guy, avoid writing code at all costs :)

$parse = new AmazonLiteXMLParser($rxml);
$records = $parse->getRecords();

If you continue to use Perl, look at Template::Toolkit. I use it for
all sorts of things, everything, really nice.

Good idea, bad project. It is good that you diversify your knowlegde if
that helps your career but I think it is not a good idea to make
technology shift in a project that is already written and working well
in a certain language. I would say the same if the project was written
in Perl and you wanted to change to PHP to diversify your knowledge.
I recommend that you do that in a low risk project that you can start
from scratch. If you do the change now, chances are that you will face
many difficulties and a lot more work than you could antecipate.

There is no evidence that is true. Maybe that is just your experience
but doing what you mentioned in PHP is a day at the beach.
Reading from stdin is the same as reading from any file. Just use
fopen("php://stdin","r") to get the file handle.
There are many ready to use components to parse complex e-mail if that
is what you want. If you just need to use regular expressions, you can
do that easily in PHP.
I can tell you that I do that myself in a site of mine and probably
handling more complex situations like handling bounced newsletter
messages. I do it all with PHP hands down. I do not see where Perl would
be better.
Maybe that is my lack of Perl of experience compared to PHP experience,
or your lack of PHP experience compared to your Perl experience.

My opinion is that switching to Perl in the middle of a project that
already works well in PHP would be a major mistake. You may want to try
it and realize that yourself at the expense of loosing a lot of time and
probably make your employer very nervous.
Regardless if you switch the language, you will always have trouble to
split the business from the presentation logic from your PHP scripts. My
advice is that you do that just splitting the logic in scripts that you
really need to do that. Resist the temptation of doing that in all scripts.
Also, doing that and switching to a new language at the same time would
make it worse. A sure recipe for disaster. Better safe than sorry.

True, I see that now. I guess I should have sent my email to the

Yeah, I'm actually on the phpclasses mailing list, so I think I know

That is a factor, although I'm no Perl expert either... Sometimes I
fall in a trap when it comes to projects...I start focusing on what
would be cool and fun to implement and sometimes I lose sight of
what's best for the project...

I'll be honest, I didn't forsee the duplicated business logic problem
(although I should have) until I was too far along with Perl to change
my mind. I didn't lose any time, though. It would have taken me
about the same amount of time to implement it in PHP, simply because I
had to learn a lot about email handling and MIME messages, etc. These
were training issues that I had to get past that were not
language-specific.
I also have the advantage of having an employer who isn't a programmer
so is fairly oblivous to the details of implementation. He's
basically an end user who tells me how he wants the program to
function and leaves it up to me to make it work. This can be a big
advantage because I have almost absolute freedom to do what I want,
but it can also be a disadvantage because I sometimes get carried away
with all that freedom. :-)

Ok. It is hard to know when you are not abstracting and modularizing
things enough, and then when you are doing it too much. Often I'll go
to extra work to make something scalable, and then we end up never
touching it again. At other times I will bang something out quickly
thinking it's a one shot thing and then I find out it needs to be
expanded. Ah well, I guess I shouldn't complain, it pays the bills...
:-)
Thanks for the response...

Something like CORBA looks good to me, although it's most likely over
my head at the moment. It would probably offer the advantages of
SOAP/XML-RPC and do it without all of the overhead. But PHP support
for CORBA looks to be pretty shaky. The only reference I could find

Look through the MySQL functions. I seem to recall that there is a
function for just about anything, and all you really want to do is find
how many rows are in all the tables in a particular database. Thus, a
couple of loops is all you need, with the outer one looping through each
table (obtained from a function) and the inner one doing a select
count(*) or a mysql_num_rows().
Happy hacking.

<?php

$sql_result = mysql_query($sql, $connection) or die ("Could not get Query");
$row = mysql_fetch_array($sql_result);
$sUsers=$row["count(*)"];

Then do a SHOW DATABASES query before that and loop through the results,
counting the rows in each table.
If you have to do this, though, I think you have some normalization
issues with your database...

oh my god. here is an example.
$userLevels = array(
1 => 'Member',
2 => 'Admin',
4 => 'Writer',
8 => 'Expert');
$cat = 15;
for ($mask=1; $mask <= 64; $mask *= 2) {
if ( $mask & $cat ) {
print "Yes $mask is in $cat\n<br>";
}
}
here i didn't have to 'or' the IDs but it works fine
and i didn't really understand how it works?
what does it mean "if 2 & 15, 2 can be found in
15"???!!! is that a miracle;)

Yeah, this through me as well. Using Perl I got completely out of using
quotes when not essential, still don't like em. But the php.net site's
got the answer:
http://www.php.net/manual/en/language.types.string.php
someone put a link to another good explanation:
http://www.zend.com/zend/tut/using-strings.php
And of course take care of the magic (imho, black magic) that can go on
with auto escaping, quoting etc. that I should fathom but haven't.
the php.net site is wealth of info, good search, I find 98% of my
answers there.

Hi,
Read up on the image manipulation functions of PHP at
http://www.php.net/manual/en/ref.image.php
You will need to install the GD library if it's not already installed and
once you do you will have access to all the functions described, including
the ImageCopyResized function. To read the image from disk, you will
probably have to use ImageCreateFromGif or ImageCreateFromJpeg and to
create the destination image you will need to use CreateImage. You can then
save the resulting thumbnail using ImageGif, ImageJpeg or anything you like.
Just as a side note, you should probably use ImageCopyResampled which uses
interpolation to resize the image, thus creating a thumbnail of much better
quality.
HTH
Olivier
PS: to get the image's height and width, use ImagesY and ImagesX
respectively, once you have opened/created the image.

Not sure if this has been answered yet but since the new version of PHP,
I found that it doesn't like you entering the SQL statements in the
query tag directly. Here's what you should do.
$sql = "select password(".$_POST['password'].")"
$conn = **YOUR DATABASE CONNECTION**
$result = mysql_query($sql, $conn);
while ($p = mysql_fetch_array($result, MYSQL_ASSOC)):
$pswrd=$p['password('.$_POST['password'].')'];
endwhile;
Remember to replace **YOUR DATABASE CONNECTION** with, evidently, your
database connection. What I usually do is assign a function
(db_connect()) to connect to the database and select the database then
just put $conn = db_connect().
Hope that helps!

Im running a dev box with IIS 5/Apache/php 4.1.2
I just noticed that part of a script that is supposed to delete a file
isn't working under IIS but is under Apache.
Under IIS, php is installed as isapi.
Paths are correct, and the file in question is created by the script and
according to the permissions, SYSTEM has full access to the file.
MARC and user notes under unlink() didn't reveal anything about why
unlink() works for some and not for others.
Code snippet in question ->
--------------
$log = '../../includes/error/error.log';
if (isset( $_POST['Reset'] ))
{
if (!unlink($log))
{
trigger_error('UNABLETORESETLOGFILE' , E_USER_WARNING );
}
}
Can anyone shed any light for me.
Thanks for any insight you may provide.

One of the Funktions is going to be the possibiliy that the page admin can set an

My Problem is, that I have to change more than one value at a time due to the Listing,
where all
customers are listed in one big list.
So I have to write multiple values in to the database as Update.
I don't have a clue how to do this, the only thing i could do is

Hi Randy,
It means that you are calling the function without the right amount of

Hi,
Anyone know if it's possible to call a class function using 2 string
variables WITHOUT instantiating the class?
i.e.:
$clName = "myClass";
$fuName = "myFunc";
$clName::$fuName();
I have tried several different combinations of eval and {} and just
about everything else I can think of… and they all give parse errors
when the class name is a string var. (i.e. myClass::$fuName() works fine
(as expected) but $clName::myFunc() does not). Everytime it doesn't
work, it just gives a simple parse error.
Any suggested are much appreciated!
Thanks in advance!

Nevermind, I have finally figured it out... I was missing a ; in the
eval statement.
For anyone who wanted to know, there's 2 ways...
1) the long way
$clName = "myClass";
$fuName = "myFunc";
$t = new $clName;
$t->$fuName();
unset($t);
2) the short way
$cl = "myClass";
$fu = "myFunc";
eval("$cl::$fu();");

Subject: [PHP] Calling class functions using string variables?
Hi,
Anyone know if it's possible to call a class function using 2 string
variables WITHOUT instantiating the class?
i.e.:
$clName = "myClass";
$fuName = "myFunc";
$clName::$fuName();
I have tried several different combinations of eval and {} and just
about everything else I can think of… and they all give parse errors
when the class name is a string var. (i.e. myClass::$fuName() works fine
(as expected) but $clName::myFunc() does not). Everytime it doesn't
work, it just gives a simple parse error.
Any suggested are much appreciated!

Hi,
the following PHP script causes me trouble:
<?php
session_register("bunt");
phpinfo();
?>
This is just a simple example. The problem is that the script produces
no output at all when called with the browser. I could use
<?php
session_start();
echo "test";
?>
instead, but I won't get any output either.
Everything works as expected when session_start() or
session_register() are not used --- phpinfo() then says: Apache/1.3.22
(Unix) Debian/GNU PHP/4.1.0RC2.
Any help would be appreciated; thanks in advance!

Is it possible that display_errors is set to "Off" in your php.ini?
If this were the case, perhaps a fatal error is occuring when you call
the session functions but you aren't seeing it because of the
display_errors setting...?

Georgie,
I'm not sure what you're wanting to do here, but it looks like you just
want to use PHP to write some javascript. There's no need to make the
browser request an additional page for this. Just do something like this
in your PHP script:
<script language="javascript">
<?
PHP stuff here - output is valid javascript
?>
</script>
or even:
<script language="javascript">
<?
include("/home/georgie/top_stuff.php");
?>
</script>
However, speaking directly to your problem, see what you see when you
access that URL (http://localhost/top_stuff.php?affiliate=1) yourself.
If your PHP scripts are not being processed and instead are just
displayed in the browser, then your Web server is not configured to
process PHP.
Happy hacking.

The Javascript has to be called from other servers, some who might not even
support PHP. And yeah, when you actually visit the URL, it displays perfect
JavaScript
Thanks anyway

Georgie,
Then what you're doing should work perfectly fine. Can you give more
details about the error received?
The reason I ask is because a Web browser will submit the exact same
request for that URL that you do when you type it in yourself. Thus, if
you don't see any PHP code, neither should the browser when it tries to
execute that as javascript.

Solved the problem.
In case anyones wondering,
I had the PHP script starting with a <script> and ending with </script> when
I already had that done in the HTML page.
Simple

Georgie:
So just for clarity, this "PHP" script
("http://localhost/top_stuff.php?affiliate=1";) was actually a file
containing javascript? and no PHP?
And out of curiosity, if that is so, why append the file name with
".php"

Hello everybody,
Getting the following error when trying to generate a pdf file.
Fatal error: PDFlib error: function 'PDF_set_info' must not be called in
'object' scope in E:\php\pdf.php on line 6
>From what I can tell (google and php manual online) this error is caused
when your webserver (IIS 5 in this case) doesn't have write permissions to
the directory.
This is NOT the case here as far as I can tell. Other scripts I run write
just fine and as seen in the below code, 'abc.txt' is written with no
problems before the script dies with the above error.
Any ideas?
-Peter
<?php
$fp=fopen("abc.txt", "w");
fwrite($fp, 'test');
$pdf = pdf_new();
pdf_open_file($pdf, "e:\php\test.pdf");
pdf_set_info($pdf, "Author", "Uwe Steinmann");
pdf_close($pdf);
pdf_delete($pdf);
echo "<A HREF=getpdf.php>finished</A>";
?>

Validate the input BEFORE outputting anything to the browser... this way you
have control over such problems.
<?
// validate
// code
// here
if($valid)
{
header(...);
exit;
}
?>
<HTML>
<?
if(!$valid)
{
echo "error on form";
}
?>
</HTML>
The code below exit; will only be executed if the input was NOT valid....
Regards,
Justin

header() does work in this circumstance. In what way do you think it
doesn't?
header("Location: http://www.google.com/";);
exit;
Include that code "after parsing", and your users will be redirected to
Google's Web site. I'm not aware of any Web client that does not support
this, regardless of how old or uncommon.

You'd be hard pressed to find any difference in how the server reacts to
either. You'll generally have better luck in some search engines if you
use example 2. But onless you've got some strange reason hording
all of your code in one file, I can't imagine any reason why example
1 would be of any use / advantage.

That's easy! Modular site building.
Ever hear of Fusebox for PHP and ColdFusion (www.fusebox.org)? Corral for
Lasso (www.corralmethod.org)? These and other frameworks allow for rapid
construction of complex sites by reusing elements and conditionally doing
things on the fly! (among other stuff)
But you are correct, search engines tend to not think sites built this way
are very deep. So "alternate" URL coding should be considered in every case!
Good luck.
