In a response to your previous posts on this matter, I suggested that you
search freshmeat/sourceforge for a PHP-based media file metadata extractor
(yes one does exist). I'm putting forward the same suggestion again.

Ok, Ill look, but not sure what good it will do me, as Im already
reading a file's metadata (using my own code).
Im basing my assumption, on that binary data may share so called "magic"
bytes.
Like an mpeg header (11111111111) may/or may not appear in other file
formats. (Purely an assumption as of this moment)
But thanks for reminding me on the other code...

I hope your not using that 11111111111, that isn't correct for an mpeg
file.
I would also point out that even if the magic was unique and you could
tell that the file was the type it is suppose to be, the person can
still put invalid data inside there. Like wrap a jpeg header and eof
marker in there but have an executible within it.
Some file formats have crc's built in, like mp3. You could also run a
crc check on the files if its available. I believe avi's do to, but i'm
sure since this isn't reliable it isn't going to be a reasonable
solution.
Another thing to do to garuantee the file would be to decode the format
and then reencode it ie(mpeg, mp3, jpeg, gif, etc). then again this seems
like overkill and plus with lossy formats like mp3 and jpeg you'll lose
quality.
I'm not sure if this is a big issue for you, I just thought I'd point
that out.
any way, thats just a few comments i had on that
Curt.

It beats me why you're not storing the info in a DB rather than a file.
Anyway here's some psuedo-code:
$file = file('file);
foreach ($file as $line => $data) {
$file[$line] = trim($data);
if (!strcmp($what_you_are_looking_for, $file[$line])) {
// found, do your replacement stuff
}
}
implode('choose a suitable EOL character(s)', $file);
write_out_file();

These files were already done from last year, so I figured I would just
carry on with them. Last year they did not have to be manipulated - so
it wasn't a big deal. I have since changed the whole thing and am now
using a database (took me a whole 45 minutes), which I was using anyway
to hold all my other info. I'd still be curious though as to why the
other way did not work.

Hi,
I apologize for all the emails on this, but I'm truly at a loss here and
really need some input as to what I need to do to get this working.
I have a FORM with two drop down menus and have the entries saved in two
separate .inc files i.e:
<Option Value="3">Alfredsson
<Option Value="39">Arnott
<Option Value="150">Aucoin
<Option Value="143">Audette
Etc...
<Option Value="67">Bates
<Option Value="36">Battaglia
<Option Value="152">Berard
<Option Value="6">Bertuzzi
Etc....
The user enters the webpage and chooses a player from list one and list
two. This gets submitted to my PHP script which reads in these files and
manipulates them accordingly and re-saves them. At the end of the PHP
script I include the input file again - include("injury-input.php") -
which should now have the updated drop down menus.
This seems to work the first time you open up a browser and go to the
input page (although I can't really even be sure of that now). If you
try to do it again using a different set of players, it doesn't work. I
usually end up with two empty files. So it appears it is opening the
file the second time ok, but is not writing to it.
I have no idea what to do with this.
Here is the script:
function writeplayer($from_row, $to_row) {
include("trade-errors.inc");
$filename = "players.inc";
$fd = fopen ($filename, "r");
$content = "";
while (!feof ($fd)) {
$content = fgets($fd);
if (preg_match ("/".$to_row['player']."/", $content)) { }
else { $list[] = $content; }
}
fclose ($fd);
$num = count($list);
$list[$num] = "\r\n<Option
Value=\"".$from_row['idp']."\">".$from_row['player'];
$num = count($list);
$list = preg_replace('/(<.*?>)(.*)/', '$2$1', $list);
sort ($list);
$list = preg_replace('/(.*?)(<.*>)/', '$2$1', $list);
if (is_writable($filename)) {
if (!$fp = fopen($filename, 'w')) {
$injury_errors = $playeropens;
include("injury-input.php");
exit;
}
for($i=0; $i < $num; $i++) {
if (!fwrite($fp, $list[$i])) {
$injury_errors = $playerwrite;
include("injury-input.php");
exit;
}
}
fclose($fp);
}
else {
$injury_errors = $notwritable;
include("injury-input.php");
exit;
}
unset($list); unset($content); unset($num); unset($filename);
unset($fd); unset($fp);
writereserve($from_row, $to_row);
$injury_errors = $updated;
return($injury_errors);
}
function writereserve($from_row, $to_row) {
include("trade-errors.inc");
$filename = "players-reserve.inc";
$fd = fopen ($filename, "r");
$content = "";
while (!feof ($fd)) {
$content = fgets($fd);
if (preg_match ("/".$from_row['player']."/", $content)) { }
else { $list[] = $content; }
}
fclose ($fd);
$num = count($list);
if (is_writable($filename)) {
if (!$fp = fopen($filename, 'w')) {
$injury_errors = $playeropens;
include("injury-input.php");
exit;
}
for($i=0; $i < $num; $i++) {
if (!fwrite($fp, $list[$i])) {
$injury_errors = $playerwrite;
include("injury-input.php");
exit;
}
}
fclose($fp);
}
else {
$injury_errors = $notwritable;
include("injury-input.php");
exit;
}
$injury_errors = $updated;
unset($list); unset($content); unset($num); unset($filename);
unset($fd); unset($fp);
return($injury_errors);
}

what is list after the first preg and after the second one, that regex
doesn't look safe to me.
Do you have access to a database? This task would be a whole lot easier
to do, plus a whole lot more safer.

Done. You must have read my mind. I just finished putting the whole
thing in MySQL - since I am using it anyway to hold all my other data it
was easy to do. Took me about 45 minutes to do this as opposed to a week
with the other, and it still didn't work. I'd still be curious to why
the other is didn't work though. I know my logic is correct, but maybe
what I was trying to do just wasn't feasible.
Thanks for the input.

Im programming for a few years now in PHP. After trying to use classes i
dont see their point either. In most cases if i need a class-like structure
i do something like this:
function thing_new() {
return ++$GLOBALS['thing_resource'];
}
function thing_put($stuff, $res=NULL) {
if (is_null($res)) $res = $GLOBALS['thing_resource'];
$GLOBALS['thing_stuff'][$res] = $stuff;
}
function thing_get($stuff, $res=NULL) {
if (is_null($res)) $res = $GLOBALS['thing_resource'];
return $GLOBALS['thing_stuff'][$res];
}
Because there is no constraint to be more OO like in Java it doesnt makes
sense. And this way you are more flexible.

Classes are good in that they group functions and variables into a re
usable block. Trying to do everything by just loading functions will
eventually lead to naming and include hell once you start doing
complex things.
PHP might not be an oo language but it sure helps me keep things
togeher. I tend to make classes that do a function like
authentication, I just need to include authClass.inc and fire it up
and all my auth work is done. i know I can create other functions as
they won't clash with the ones in the auth class.
Another great thing with classes is you don't have to make common
variables global all the time.
If you haven't used any other type of OOP then you won't have any
problems trying to make PHP look like java, you can just grab the
benifits with whats available :-)

Hi,
I myself never really create classes to use in my projects, if I ever use
classes its only because they come from someone else (eg phpclasses.org), I
find using the non OO approach much easier to understand.
Just my 2 cents.
Cheers,
-Ryan

The biggest thing classes do is resolve name space issues, even with
this method you have namespace issues with your function name and your
variables. This rather effects a lot of people who create libraries to
share with.
A big downfall with classes, however is there speed. Benchmarking a
function call vs. a class->method call, results in a significant
difference and even more if your using a lot of classes.
In general, I only use small and nicely bundled classes that don't have
to do a lot of work, ie authentication, session.

And besides php wasn't designed/developed to be an OO language.

Sure i have to add and take care of the namespaces myself, but thats it and
the amount mental work compared to designing a class is imho lesser in my
way. And most times only 1 object of a class gets instanciated, which is to
much overhead in an application. And then u dont even need my construct.
And if you dont create an object and call the function in an static way
(via ::), then the whole benefit of the associated data is gone anyway and
the only thing you have is the namespace. So i dont give the Parser the
challenge of preparing a class representation and keep it simple. And at
last: no more copied objects.

I am using Apache 1.3.27 and PHP 4.3.3.RC1 and someone has told me that
my web page cannot be cached but I cannot figure out why. My friend
tells me my pages all keep sending this in their headers:
Cache-Control: post-check=0, must-revalidate, no-store, no-cache,
pre-check=0
But I can't figure out why the headers are set like this. I am not
setting any headers so I am wondering if it is a setting in my web
server, php.ini file or some other php scripts I have running in the

Also print_r($HTTP_SERVER_VARS) gives one server variable to be:
[HTTP_CACHE_CONTROL] => max-age=0
What does this variable mean and where was it set?

In most cases you dont want your php output to get cached, and so php
will do this automaticly. You can stop that from happening by sending
the same header with public as the paramater:
Cache-Control: public
You also might want to set a few others:
/* if you are sending a file send the last modified time */
'Last-Modified: ' . gmdate("D, d M Y H:i:s", $unix_ts . ' GMT')
/* for old ie bug and older proxy caches */
'Pragma: no-cache');
/* if this applies */
'Expires: '. gmdate("D, d M Y H:i:s", time()-(1200). ' GMT')

Hello,
fist, I want to introduce myself. I am 24 years old, studying media
science in Germany (Trier) and working with PHP for 5 years now.
My question is about the dbx module in PHP.
Is there any possibility to use it with mysql-command: LIMIT?
There are similar commands vor postgres etc. but I didn't find anything
for that in dbx_query either.
Greetings,
-sebastian

It's more than likely register_globals that is off.

just a few more tips.
the following ensures that an form input field by the name of 'sentence'
is actually sent via method=post, otherwhile you can escape it.
this is good for low level script integrity
if( isset($_POST['sentence']) ) echo $_POST['sentence'];
you might want to also look into the following functions.
rawurldecode()
htmlspecialchars()
addslashes()
stripslashes()
chop()

Hello,
This is a reply to an e-mail that you wrote on Sat, 19 Jul 2003 at
15:25, lines prefixed by '>' were originally written by you.
Two things...
> <form method="post" action="takeform.php">
> <input type="text" value="sentence">
> </form>
Your input does not have a name attribute.
> .............

> .................
This line of code will onyl work if the name of your input tag is
sentence and register globals is switched on.

Time to find another 'serious' hosting company :-)
you may need to put this in the cgi file (if you are on a unix server)
#!/usr/bin/php
<?
include('/path_to_web/page.html');
.
.
?>
change /usr/bin to whatever directory the cgi version of php is in if
you can find out where they have hidden it.
Thanks for the response Tom. Unfortunately, that won't work either. A
little background.... I'm using Dreamweaver and their template feature.
for the site. I want to read some info out of a text file and format it
into the web page. (the hosting company doesn't support any db
either... I wish I COULD change companies, but...) So, if I use your
idea, when the html file is included in my php script in /cgi, the
images in the html file will be relative, not absolute (../images/***).
The only solution I can think of is to call the php script, have it
extract the info I need and deposit it (with html-formatting) into a
file, then have the html file include that file. Course, this will blow
up if more than one person accesses the site at the same time.
Anybody with any other thoughts?
Thanks
Dale

Here is the code I am trying to implement...
update table set col1=value where condition=true and condition=true order by
col2 desc, col3 desc limit 1;
The UPDATE command does not seem to support the ORDER BY part despite it
being listed in the instructions on the mysql.com website. Is there any
workaround to this that anybody knows of?
Thanks in advance for your help. :o)

This is only supported in versions 4 and above - if you're using 3.23 you
can get away with LIMIT in your update queries, but not ORDER BY.
Cheers
