strcoll

(PHP 4 >= 4.0.5, PHP 5, PHP 7, PHP 8)

strcoll — Locale based string comparison

Description

strcoll(string $string1, string $string2): int

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().

Parameters

string1

The first string.

string2

The second string.

Return Values

Returns < 0 if string1 is less than string2; > 0 if string1 is greater than string2, and 0 if they are equal.
