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.
注: strcoll() was added in PHP 4.0.5, but was not enabled for win32 until 4.2.3.
