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


int strnatcasecmp ( string str1, string str2 )

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.

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(), strcasecmp(), substr(), stristr(), strcmp(), strncmp(), strncasecmp(), strnatcmp(), and strstr().
