Note Submitter: Joey ---- In php5.6, if you pass an int/long to dtype_digit it will try to do clever stuff like treat it as a char (5 => chr(5)) or use convert_to_string. I suspect this means that -128..255 is false except 48 to 57. Oh and I think higher number outside that range are true because of convert to string. My advice, just don't send longs to ctype_digit unless you want to check they are ASCII 0-9 codes. This combination of behaviours defies logic, probably why it's not documented. I hope php 7 strips it out.
