Grab the time at the beginning of the page execution and then grab the time
at the very end. Subtract the two and you have the amount of time the page
took to execute.

You can't find out how long the pages takes to RENDER at all --
rendering is something that happens client-side.
You can find out how long it takes to execute a script (on the server),
which is what I assume you mean.
See Example 1 on http://www.php.net/microtime

I have a common included file with error_reporting set to 0
If I do a var_dump(error_reporting()) right after it it returns 0
In a file that includes this common file, if I var_dump(error_reporting())
there it return 2047, which I believe is E_ALL
It that the correct behaviour of error_reporting???
Thanks

Cant say why, but after doing a fresh pull from CVS, the problem seems to have
gone away.

Actually, I found the real problem.
The file that was including the common file was including it with a @ like ->
@require('./common_file.php');
Once I remove the @, the error_reporting level, reported correctly, what was
set in the included file, so it seems that while @ turns off error reporting,
after that point, it goes back to php.ini's default of E_ALL (2047)
Is it a bug, I have no idea at the moment.
Im currently running php 4.3.3. Please advise.
Thanks

No I believe that is a feature the ability to turn off error reporting. You
can do the same with mysql functions.

Yes I know about turning off error reporting, but what happens after that
point.
An example.
-- common.php --
<?php
// php.ini error reporting is set to E_ALL
error_reporting( 0 ); // sets it to 0
var_dump(error_reporting()); // Returns 0
?>
-- foo.php --
<?php
@require('./common.php'); // Here is the problem
var_dump(error_reporting()); // Returns 2047
?>
If I remove @ from require('./common.php'); in foo.php,
the var_dump() then correctly reports it as 0 instead of 2047
Kinda goofy if you ask me...

Hiya fellow PHP coders!
I have a problem. I need a function to parse mIRC-colorcodes with PHP.
Unfortunaly, I'm not capable to do this myself (or I'm thinking too
advanced or something).
The code is built like this; chr(3) starts the color formating. After
that sign, a series of numbers will come. Can be one or two digits
(1-15). 0-9 can have an additional zero before it, like 00-09. Each of
these number represents a color.
00 = White
01 = Black
02 = Dark Blue
03 = Dark Green
04 = Red
05 = Marron
06 = Purple
07 = Orange
08 = Yellow
09 = Green
10 = Teal
11 = Cyan
12 = Blue
13 = Magenta
14 = Dark Gray
15 = Gray
Now, to make it even worse, it's possible to use a background-color for
the text. This is added with a coma. So, the syntax is "X4,8String"
where X is really chr(3). Red (4) String with yellow (8) background.
The colorparsing can stop when another occurance of chr(3) commes up.
Also, the colorparsing ends at the end of line.
Please help me on this issue.

I'm not a regex guru, but |[0-9]{2},[0-9]{2}(*.?)| should capture it. I
forget how to ask the regex for optional items, but that should get you
started.

I haven't tried this before, but I need to now and wanted to get a couple of
pointers.
I have a client that maintains a MySql database on a webserver. They want to
import data into the database by uploading a Excel spreadsheet (most likely
saved in a .csv format). I want to import the data directly into the data
table via a php script. It appears that I should be using a LOAD DATA INFILE
command or a MYSQLIMPORT command.
>From reading documentation, it would appear the the LOAD DATA INFILE is the
way I would have to go as MYSQLIMPORT appears to be a command line only
command.
I could use some pointers from someone who has used this before....such
as...
1. What is the default file format expected? (.csv?)
2. Any quarks I would need to know about?
3. Etc...

Doesn't really matter, as long as it's text/plain, and you know what the
deliminter is (.csv usually is comma). It's been a long time since I
used Excel, but I think you can specify the deliminter when exporting,
and if that is still the case, I would go with a pipe (|). Commas are
far to common in data to be used as a seperator IMHO.
2. Any quarks I would need to know about?
Not to my knowledge.
3. Etc...
No need to reinvent the wheel, check places like
www.phpresourceindex.com to see if they already have a function / class
to do what you need done.

Hi,
I am experiencing a strange error while using PHP 4.3.4RC2.
In the apache2 log, I read:
fatal: cannot realloc() 1937201923 bytes.
I do NEVER try to allocate such memory.
I think the problem is related to some serialize/unserialize() code I am
using (in fact, removing serialize/unserialize block makes the script
work perfectly).
Is there anything I can do to test _exactly_ where the script bombs?
Ciao,
Fabio

Hi all,
I'm trying to write a script to get the next last friday of the month and I
am failing miserably. It keeps giving me October 10th. So, I scrapped it.
Basically, I just want to show what the last friday of the month is, and if
that date has already passed, show the last friday of the next month.
How can I do that?

Search for 'doomsday algorithm' on google. Once you grok it, you should be
able to figure out the last friday quite easily.

You can get the number of days in a month from date()
Now you know that the last Friday of the month will be at most 7 days
from the end of the month,
loop through the last 7 days of the month and determine what date it is
using the date() function.
Compare the date to determine if it is Friday or not.
And then add in the check for if the date has passed or not.

The last friday of the following month will be the last friday of the current
month + the number of day in the current month > 28 ( date("t") - 28 ).

OOPS! I meant the The last friday of the following month will be the *date*
of the last friday of the current month MINUS the number of day in the current
month > 28 ( date("t") - 28 ), + 7 days if not in last 7 of month.
i.e.,
Last friday of October is 31
Last friday of November is 31 - (31 - 28) = 28.
Last friday of December is 28 - (30 - 28) = 26.
Last friday of January is 26 - (31 - 28) = 23 + 7 = 30
because 23rd is not in last 7.
Last friday of February is 30 - (31 - 28) = 27.
etc...

I started writting an install script that would talk to a PHP script on one
server while being used on another.
So you would have http://www.someserver.com/install.php -->
http://www.homesever.com/install.php via CURL without the users knowledge.
The script would pass certain variables and if one didnt jive then the
install would stop and a message would be sent back. If everything was okay
then the client would have the rest of the source ftp'd to the
http://www.someserver.com server and the install would continue until
everything was finished. I have done very little with CURL, I'm not sure if
there are any tutorials or anything else that I could see to get some good
examples of both ends of the process anyone know of any? Anyone know of a
better way? I'm also looking into XML or Java on the authorization end but
not sure yet.
thanks.

if you want to use xml and php you can use soap and then you can
incorporate other languages as well...making soap the common protocol
via http.
most languages support soap implementations of one sort. should be
worth your time to look into soap.

Apologies to anyone also subscribed to php.xml.dev, who will have read this
earlier, but it doesn't seem as frequently read as this news group... so I
am reposting...
Hi
I want to write a function that will take any SQL query as a parameter, and
generate XML that represents the recordset.
e.g. "SELECT * FROM Customers"
returns:
<recordset>
<record id="1" name="Mr Smith" purchases="2"/>
<record id="2" name="Mr Jones" purchases="25"/>
<record id="3" name="Mr Davis" purchases="7"/>
</recordset>
There are two approaches I think. One is to use the XML DOM, the other is
simply to join lots of strings together. What is the best approach?
Thanks (and this is my first post to a newsgroup, and my first post to this
one, so excuse me if I've missed something vital!)

If I were you I'd just join strings- it's much less resource intensive. Just
make sure you're using valid XML.

What i have done in the past is use the dbx extension in php to do my
queries. Then i have iterated over the multi-dimensional arrays and
created xml tags with the values for the dbx result set.
You can use this type of logic with any db functions and just create xml
data.
If you have an xml record that is very specific you can use sprintf to
create something like:
$record = '<record id="%d" name="%s" purchases="%d"/>';
while( $row = database logic here ) {
$records[] = sprintf(
$record,
$row['id'],
$row['name'],
$row['purchases']
);
}
Then use the array functions to merge, sort or whatever you like...
That should get you started...

Hi,
As Ray has also mentioned sprintf() is the best approach. I would also
like to point out that you would be doing three iteration over your data
so please make sure that your queries are not just 'select * from
customers' but 'select * from customers where something=something'
all the best

If you are lucky enough to be using mysql ver 4.x+ -- it has this

Sample run :

If your mysql version is < 4.x -- then you have to resort of one of the
many mysql-to-xml classes available (check phpclasses.org and PEAR).

Hi,
I got a small question concerning a parser I'm working on.
While the parser goes through the text it hits different tokens, which are
the processed by functions.
There are global settings which set if a function should be called or not.
(For example one time I do not want to edit token A, the other time I only
want to edit token A).
I thought that it would be cool if the algorithm that sends the tokens to
the functions would be generated on the beginning of the script, only
putting in those functions which will be called on this specific run.
Now the main question is, is this really going to bring me a performance
tune up, or am I running for extra work that won't pay out?
Then I thought of how to implement this.
The only solution I know is creating a new script file which will be
included after it has been dynamically generated, but I guess that will be
to slow.
So is there a possibility of executing strings?
e.g. putting an if clause in a string and then executing it.
Thanks for any info...

Hi,
Is there an IF LIKE statement in PHP? I've got a MySQL database setup with
headings and text (think a news article site) - headings in one field, text
in another. In some cases, I don't want the contents of the heading field
to appear on the site - in these cases, the headings begin with 'noshow-'.
So I'm thinking the easiest way to handle this is if there is something
similar to the MySQL 'LIKE' command in PHP ... is there such a beast?
TIA
-Tim

if(preg_match('/^noshow-/', $heading)){

I'd concatenate the employee's email and manager's email, and then use an
MD5 hash of it as the unique string. i.e:
$unique_id = md5 ( $employee_email . $manager_email );
For more info on what MD5 is, see

Remember that there's no guarantee that any two strings won't map to the
same md5 hash, and so they are bad candidates for unique ids.
Even allowing for that, concatenating only the email addresses makes the
hash extremely vulnerable.
Better to add a salt and a timestamp, so your unique string becomes
something like:
unique_id = unix_timestamp + md5 (employee_unique_token +
manager_unique_token + random_string)
(All this assumes that you want the unique id to be unguessable for some
reason. Personally, I'd just put the primary key associated with the job in
the URL, and password-protect the site. Much simpler.)

Afternoon all,
Is it just me, or would everybody else like to see a case-insensitive string
comparison operator introduced into PHP? It is a type of comparison that I
use a lot, and having to strtolower() everything before comparison can
impact code readability, not to mention the angst, pain and trauma of having
to repeatedly type 'strtolower()'.
Assuming this new operator is something like '=*', the following two lines
of code would be functionally identical.
if (strtolower($a) == strtolower($b)) echo "The same!";
if ($a =* $b) echo "The same!";
Of course creating a new operator is only justified if the vast majority of
PHP users do these comparisons as much as I do, and are as averse to work as
I am ... :).
Thoughts?

I was feeling generous so I went back in time and added this
functionality to PHP as of version 3. I call it the "strcasecmp"
function. I placed the description and usage of the function in the PHP
manual: http://www.php.net/strcasecmp
Hope you like it!

You could use the strcasecmp() function as well:
http://ca3.php.net/manual/en/function.strcasecmp.php
<?php
$var1 = "Hello";
$var2 = "hello";
if (strcasecmp($var1, $var2) == 0) {
echo '$var1 is equal to $var2 in a case-insensitive string
comparison';
}
?>
Cheers,
Pablo

That was nice of you, but he wanted an operator.

I need to copy a directory from one location to the other. I didn't find a
function for this. Is copy() supposed to work on directories as well as
files, or is there another?

Hey!
i did few upgrades on my server and i got into some weird problem.
what i did was:
Upgraded to: Apache2
Upgraded to: php 4.3.3
and after that GD stoped working...
i did check on phpinfo(); and it came up with:
gd
GD Support enabled
GD Version bundled (2.0.15 compatible)
GIF Read Support enabled
PNG Support enabled
WBMP Support enabled
XBM Support enabled
Was there any problems or anything that i missed after gd upgrade and php
upgrade? i tried to look at change log but didn't find anything that would
solve it, its just gd doesn't work and i can't fix it, php just doesn't
recognizes gd functions.
So does anybody know what problem could be? or any links that i should check
about new updates in versions?
Thanks!

In the context of your questions, 2-Dimensional arrays are no different to
1-dimensional arrays.
All global vairables in PHP are stored in the predefined $GLOBALS
associative array, which is automatically global in scope. Each key of the
$GLOBALS array is a name of a global variable. For example, the following
code will print "Hello World":
<?php
function setVarA ( $value ) {
$GLOBALS['varA'] = $value;
}
function echoVarA ( ) {
echo $GLOBALS['varA'];
}
$varA = "Hello";
echoVarA( );
setVarA ( " World");
echo $varA;
?>
Passing an array to a function is no different passing a scalar variable:
<?php
function countArray ( $arrayArgument ) {
return count ($arrayArgument);
}
$array = array ('a', 'b');
echo "The array has ". countArray($array) ." items.";
?>

Al
