How to make dynamic signutures with stats

**Naromaru** · Apr 22, 2009, 18:41

I was wondering how would i make a image like
http://www.fpstactics.com/sig/custom/killa/1912428.jpg
I know this is coded with PHP
But how would i make this, i think all the codes are pulled from
http://clan.subagames.com/charstat_cf.aspx?usn=1912999
But witch codes?

Also how would i make a engine which would allow my users to make there own by inserting there USN? (number at the end of the link)
Kind of like

You fetch the contents of the page:

PHP Code:


$html = file_get_contents("http://clan.subagames.com/charstat_cf.aspx?usn=1912999");

Then use regular expressions to extract the text you want from the HTML.

Then use PHP's image manipulation functions to create the image and output it to the browser.

Hey can you do a tut on how to do this? i get lost with the first link
(For Subagames)

The second link is a tutorial for writing patterns for the first link. If you want someone to code the whole thing for you, then put out a Looking to Hire listing in the marketplace.

You can use the GD library to draw the signature:
http://php.net/gd
Take a look at the many examples and test them out to get the hang of how it works.

When you know how to work the API, design something nice in your favorite graphics editor, export it to a PNG file, load it in with GD in your script, and manually position all the text and such. After you're all done, you might want to convert the PNG file to a GD file (you can do that with PHP's GD library too) for performance reasons (though I don't know if it has a noticeable effect).

To take in a USN, you just use $_GET like you would normally. In the image you linked, it doesn't have a query part in the URL though. If you use Apache, you can use mod_rewrite to fake URLs and make them redirect to your script (#####.png => signature.php?usn=#####). Shove this into a .htaccess file:

Code:

RewriteEngine on
RewriteRule ^([0-9]+)\.png$ signature.php?usn=$1 [QSA,L]

(After you get all of this working, you want to save the signature images to disk temporarily because it's costly to have to re-generate this image every time. To save bandwidth, there are some HTTP headers that you want to send to make browsers cache your image, but you can ask about these things later.)

Ok so this is what they use for the kill count
<tr>
<td align="left" valign="top" class="stylenav13">Total Kills</td>
<td align="left" valign="top">9805</td>
</tr>

so would i type in

$html = file_get_contents("http://clan.subagames.com/charstat_cf.aspx?usn=1912999ctl00_Main_lbl_enemy_kill_cnt");
?

Also can someone explain the php GD and what it dose? (or link me to a more nooby guide)
Thanks in advance

No, you don't change the URL, it's not that easy.

You write a regular expression which matches the 9805 in $html.

So how do i trigger a regex? (regular expression?)

The 9805 changes so would i have to make something like
int preg_match ( string $<td align="left" valign="top">9805</td>
, string $
[, array &$match[, int $flags [, int $offset ]]] )
?

<html>
<?php
$html = file_get_contents("http://clan.subagames.com/charstat_cf.aspx?usn=1912428");
$subject = "0-9";
$pattern = '9805';
preg_match($pattern, substr($subject,3), $matches, PREG_OFFSET_CAPTURE);
print_r($matches);
?>
</html>

Sorry im spaming :3

Ok so far i get
Make the file name name.php
then
<html>
<?php
$html = file_get_contents("http://clan.subagames.com/charstat_cf.aspx?usn=1912428");
?>
</html>
And thats it
