preg_match help

[Porl123]

I've got a script when it logs into an account using cURL, stores the page in $buf with htmlentities so preg_match can read through the source, but I'm not too good with preg_match so I think this is probably completely wrong. Would somebody be able to show me how I'd fix the below to find characters a-z (any case) and digits 0-9? I think you should be able to see what I'm trying to do here

 

preg_match('%<td><a href="profile.php?u=([a-Z0-9])">([a-Z0-9])</a></td>%', $buf, $matches);

 

If you can help me at all it will be appreciated, thanks!

example for you mate.

<?php

$buf='<a href="profile.php?u=ASDfrgt234">ASderfDe1276</a>';

if(preg_match("/^(<a href=)\"(profile\.php)\?(u)\=[a-z0-9\"\>][a-z0-9\<\>]/i",$buf)){

echo "Valid";	

}else{

echo "Not Valid";
}

?>

Sorry I posted the wrong regex

 

<td><a href="profie.php?username=(.*)">(.*)</a></td>

 

Does anyone know how I can get those returns?

preg_match('~<td><a href="profie.php?username=([^"]*)">(.*?)</a></td>~',$buf, $matches);
echo "<pre>"; print_r($matches); // to see the array structure of your returns

[Porl123]

It's weird though. That should work but it's not returning anything =(

[.josh]

well I do notice the string you provided for the pattern says profie.php perhaps you meant to have profile.php ?

[Porl123]

Yeah I saw that before but it's till return nothing =( everything's should be working

[.josh]

then post an example of the content
