strnatcasecmp

STRNATCASECMP(3)							 1							  STRNATCASECMP(3)

strnatcasecmp - Case insensitive string comparisons using a ";natural order" algorithm

SYNOPSIS

       int strnatcasecmp (string  $str1, string  $str2)

DESCRIPTION

	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(3), except that the comparison is not case sensitive. For more	information  see:  Martin  Pool's  Natural
       Order String Comparison page.

PARAMETERS

	      o $str1
		- The first string.

	      o $str2
		- The second string.

RETURN VALUES

	Similar  to  other string comparison functions, this one returns < 0 if $str1 is less than $str2 > 0 if $str1 is greater than $str2, and 0
       if they are equal.

SEE ALSO

       preg_match(3), strcmp(3), strcasecmp(3), substr(3), stristr(3), strncasecmp(3), strncmp(3), strstr(3), setlocale(3).
