strnatcasecmp - Case insensitive string comparisons using a "natural order" algorithm
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.
The first string.
The second string.
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.
