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.
string1
The first string.
string2
The second string.
Similar to other string comparison functions, this one returns -1
if
string1
is less than string2
1
if string1
is greater than
string2
, and 0
if they are equal.
