PHP Equivalent of grep? Need to round up a bunch of URLs to a single page.

[TrickyPhillips]

I need to write a script that will parse through several non-static documents on my server and print out all of the URLs on those documents to a single page.

Is there a PHP equivalent of *nix "grep" that I can use to locate lines with "http://" in them?

$matches = preg_grep('#http://#i', file('/path/to/file'));

Ahh. Thank you. I was trying preg_grep earlier, but was using "include" instead of "file".

This is exactly what I needed. Thanks.
