strcoll

(PHP 4 >= 4.0.5, PHP 5, PHP 7)

strcoll — Locale based string comparison

int strcoll ( string $str1 , string $str2 )

Note that this comparison is case sensitive, and unlike strcmp() this function is not binary safe.

strcoll() uses the current locale for doing the comparisons. If the current locale is C or POSIX, this function is equivalent to strcmp(). <
