strcoll Locale based string comparison intstrcoll stringstr1 stringstr2 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. strcoll was added in PHP 4.0.5, but was not enabled for win32 until 4.2.3. See also ereg, strcmp, strcasecmp, substr, stristr, strncasecmp, strncmp, strstr, and setlocale.
