Check part of string is in_array()

[quote author="bradym" date="1211698791"]That's very similar to the validation class in CI - have you looked at system/libraries/Validation.php to see how it's done there?[/quote]

Indeed, it's the same thing I'm looking for. Should have thought about that. But hey, it's late (well, over here it is) ;-)

Thanks again!

Edit: Hmm, I spoke too soon. It's not what I need, though it comes in handy in another spot. Basically I need to find 'min_length[anything_here]'. Sorta like a wildcard.

Edit2: Come to think about it, it IS what I need. I just looked at it the wrong way.
