strcoll

(PHP 4 >= 4.0.5)

strcoll -- Locale based string comparison

Description

int strcoll ( string str1, string str2)

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 that some platforms implement strcmp() and strcasecmp() according to
the current locale when strings are not binary equal, so that strcmp() and
strcoll() will return the same value! This depends on how the PHP strcmp()
function is compiled (i.e. if it uses the platform specific strcmp() found
in its standard library!).
In that case, the only difference between
strcoll() and strcmp() is that strcoll() may return 0 for distinct
strings(i.e. consider strings are equal) while strcmp() will differentiate
them if they have distinct binary encoding! This typically occurs on Asian
systems.
What you can be sure is that strcmp() will always differentiate
strings that are encoded differently, but the relative order may still use
the current locale setting for collation order!
