preg_match help

[Lethal323]

Im trying to pull my folding@home stats from a website. I am using preg_match to search the data I pulled from the webpage. However I get the result of "NULL" whenever I try to run it!

<?php
$data = file_get_contents('http://folding.extremeoverclocking.com/user_summary.php?s=&u=454083');
$regex = "/<td align='right'> (.+?) </td> /";
preg_match($regex,$data,$match);
var_dump($match);
echo $match[1];
?>

 

Anybody know what is wrong?

$src = file_get_contents('http://folding.extremeoverclocking.com/user_summary.php?s=&u=454083');

preg_match_all('~<td align\s?=\s?[\'"]right[\'"]>(.*?)</td>~is', $src, $c);

foreach ($c[1] as $a) {

echo "{$a}";
}

Well, I wouldn't recommend using foreach, Try this sample code:

$src = file_get_contents('http://folding.extremeoverclocking.com/user_summary.php?s=&u=454083');
preg_match_all('~<td align\s?=\s?[\'"]right[\'"]>(.*?)</td>~is', $src, $contents);
echo "<pre>"; //For formatting
echo print_r($contents);

 

That will give you a better idea of the structure of what you're retrieving, as you see, there are a lot of table lines and a lot of elements that tag will give you.

When developing, always turn up your error reporting (and be sure to have display_errors as on!) to the fullest extent. Then, the (first) problem would become apparent.
