I passed the values into 'ctype_alpha', which I expected ALL output to be "Failure::xx". However, I receive "Success::xx" output on a variety of numbers from -125 to 255. Test script: --------------- for ($x = -1000;$x < 1000;$x++) { echo ((ctype_alpha ($x)) ? "Success::{$x}" : "Failure::{$x}") . PHP_EOL; } Expected result: ---------------- I expect to see nothing but "Failure::{xx}" all the way down. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=51573&edit=1
