PHP String Reference Complete PHP String Reference

Definition and Usage

The strcoll() function compares two strings.

This function returns:

  • 0 - if the two strings are equal
  • <0 - if string1 is less than string2
  • >0 - if string1 is greater than string2

The comparison of the strings may vary depending on the locale settings (A<a or A>a).

Syntax

strcoll(string1,string2)

Parameter Description
string1 Required. Specifies the first string to compare
string2 Required. Specifies the second string to compare

Tips and Notes

Note: The strcoll() is case-sensitive but not binary safe.

Note: If the current locale is C or POSIX, this function works the same way as strcmp().

Example

<?php
setlocale (LC_COLLATE, 'NL');
echo strcoll("Hello World!","Hello WORLD!");
echo "<br />";

setlocale (LC_COLLATE, 'en_US');
echo strcoll("Hello World!","Hello WORLD!");
?>

The output of the code above will be:
