# strnatcasecmp

(PHP 4 >= 4.0.0)

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

## Description

``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 infomation 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.
