[RESOLVED] Regex help?

intenz

I need to get some text in a source of a webpage. The thing is the value is always random and it's somewhere in the middle of the source.

What I need to get is:

<input type="hidden" value="123456" name="extra">

Note: 123456 is always random

I've got this...

preg_match( '/^(.+?)<input type="hidden" value="([0-9]+)" name="extra">(.+?)$/m', file_get_contents( 'http://www.example.com' ), $content );

..., but it doesn't work. The $content array is always empty.

Help?

This seems to work, even if there is a newline in the middle of the tag:

<?php
header("Content-Type: text/plain");
$text = <<<EOD
<form action="#" method="post">
<input type="hidden" value="123456"
name="extra">
<input type="submit"></form>
EOD;
$regex = '/<input\s+type="hidden"\s+value="(\d+)"\s+name="extra">/';
preg_match($regex, $text, $matches);
echo $matches[1];

Thank you for your fast reply, NogDog.

How ever, this doesn't work. I'll give you the URL.

preg_match( '/<input\s+type="hidden"\s+value="(\d+)"\s+name="extra">/', file_get_contents( 'http://www.vit.is/spsms/index.jsp' ), $content );

This returns an empty array.

I copied-and-pasted your command, added a print_r($content) after it, ran it on my PC, and it worked fine: $content[1] contained the number.

Are you sure the file_get_contents() is working for you? (Maybe url_fopen is not enabled on your host?) You might want to make sure display_errors is enabled while debugging it, or do the file_get_contents separately first and check for a false result.

url_fopen was indeed disabled. Thank you for your help. RESOLVED!🙂
