strnatcasecmp

(PHP 4, PHP 5, PHP 7)

strnatcasecmp — Case insensitive string comparisons using a "natural order" algorithm

Description

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

This function implements a comparison algorithm that orders alphanumeric strings in the way a human being would. The behaviour of this function is similar to strnatcmp(), except that the comparison is not case sensitive. For more information see: Martin Pool's » Natural Order String Comparison page.

Parameters

string1

The first string.

string2

The second string.

Return Values

Similar to other string comparison functions, this one returns < 0 if string1 is less than string2 > 0 if string1 is greater than string2, and 0 if they are equal.
