int strnatcmp(string $str1, string $str2)
This function implements a comparison algorithm that orders alphanumeric strings in the way a human being would, this is described as a "natural ordering". Note that this comparison is case sensitive.
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.
- string $str1: The first string.
- string $str2: The second string.
