Are you absolutely certain about that?
echo strcmp('These are nearly equal', 'These are almost equal'), "\n";
echo strcmp('different', 'unequal'), "\n";
echo strcmp('b', 'a'), "<br />\n";
Result:
13
-17
1
The description of the function merely says that the result is <0, 0 or >0
-- it makes no promises about the actual value when it is non-zero.
Cheers!
