PHP strcoll() Function

Hello folks! welcome back to a new edition of our tutorial on PHP. In this tutorial guide, we are going to be studying about the PHP strcoll() Function.

The PHP strcoll() function compares two strings based on locale.

Note: This function is a case-sensitive but not binary-safe.

This PHP function uses the current locale to perform the comparisons. If the current locale is C or POSIX, then this built-in PHP function is equivalent to strcmp() function.


Following below is the syntax to use this function -

int strcoll(string  $str1, string $str2)

Parameter Details

Sr.NoParameters & Description

Return Value

This function returns <0 if str1 is less than str2; >0 if str1 is greater than str2, and 0 if they are equal.


Try out the example below -

   echo "If this function returns 0, the two strings are equal.";
   echo "<br> The result is ";
   setlocale (LC_COLLATE, 'NL');
   echo strcoll("Hello World!","Hello World!");


When the above code is executed, it will produce the following result -
