Since in_array() handles different types, I don't think it would make sense to 
add a parameter that is exclusive to handling strings.

How about adding a comparitor callback then?
Maybe even overload the third argument (e.g. if it's not a boolean, then assume callback), so we can do something like:

in_array('a', array('A', 'b'), function($a, $b) { return !strcasecmp($a, $b); });

This is unlikely to be implemented; a more general solution, i.e.
a function any() or some() has a better chance, but still would
need an RFC[1].
