Re: string_find_all

This is a good idea for a script — sort of surprised it's not part of the collection already. Still considering whether or not "tootoot" should find "toot" once or twice. Obviously your way is the faster option. A simple regex query would only find it once so I guess this is good.

Thanks for the submission.

Re: string_find_all

As example:

Expand<?php
$str = 'tootoot';
var_dump(substr_count($str, 'toot'));

returns 1, so it's another vote for keeping it this way. But it would be good to have string_find_all_overlapped or something too.
