This is not true, as e.g. calling ctype_digit(48) will return TRUE. As explained elsewhere in the manual for all ctype_* functions: "if you pass an integer smaller than 256 it will use the ASCII value of it to see if it fits in the specified range (digits are in 0x30-0x39). If the number is between -128 and -1 inclusive then 256 will be added and the check will be done on that." ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=60103&edit=1
