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.
string1The first string.
string2The second string.
Returns a value less than 0 if string1
is less than string2; a value greater
than 0 if string1 is greater than
string2, and 0 if they
are equal.
No particular meaning can be reliably inferred from the value aside
from its sign.
