strnatcasecmp
(PHP 4, PHP 5)
strnatcasecmp — Case insensitive string comparisons using a "natural order" algorithm
Description
$str1
, string $str2
)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.
Parameters
-
str1
-
The first string.
-
str2
-
The second string.
Return Values
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.

The function treats '_' as after letters and numbers when it would be placed before logically.
Use strnatcmp to avoid the _ problem as mentioned below;
