[PATCH] array_combine is not binary-key safe

Hi, I don't know if array_combine() was intentionally made binary-key unsafe, but it seems wrong and inconsistent since binary keys work everywhere else I can think of -- including array_flip() and the new array_fill_keys(). And updating it is a bit of an optimization by eliminating strlen() calls. :-) I also changed the error message to be more grammatically-correct and fixed some typos in the description. http://www.realplain.com/php/array_combine_binkey.diff http://www.realplain.com/php/array_combine_binkey_5_2.diff Thanks, Matt
