(PHP 4, PHP 5)strnatcasecmp -- Case insensitive string comparisons using a "natural order" algorithm
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.
