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!
