Use strcasecmp(): strcasecmp($a, $b) // returns 0 if strings match case-insensitive // non-zero if not This is slightly unfortunate in that the test you have to do is counter-intuitive: if (strcasecmp($a, $b)): // strings DON'T match else: // strings match case-insensitively endif; Nonetheless, I'd prefer this over case-converting both strings and then comparing, as you're only making a single function call to do a comparison with in-line conversion, as opposed to two function calls for the conversions and then a comparison as well. (I guess I ought to benchmark that -- although it seems "obvious", sometimes the obvious isn't!) Cheers!
