Returns < 0 if str1 is less than str2; > 0 if str1 is greater than str2, and 0 if they are equal. strcoll() uses the current locale for doing the comparisons. If the current locale is C or POSIX, this function is equivalent to strcmp().
Note that this comparison is case sensitive, and unlike strcmp() this function is not binary safe.
Note: Added in PHP 4.0.5.
