[RESOLVED] Easy pattern match help

[shawjames]

Can someone help me with my simple pattern match:

$string = "Individual Cards (#44115)";
$pattern = "<help>\";//need help to get the number out of a string like this.
preg_match($pattern,string,$match);
print $match[0]; // should print the number 44115

The number will always be in the (#1234) part - but not always the same number of digits.

Using look-behind and look-ahead assertions:

'/(?<=\(#)[0-9]+(?=\))/'

Thank you, worked perfect! Do you know of a good source for learning about how to create matching syntax like this?

I learned the basics years ago when working with Perl to parse log files. Now I just use the PHP Manual: PCRE regex syntax. 🙂
