Re: Re: is_int/is_numeric possible bug

You could always do an is_numeric and if it returns true, cast it as an int.

That is the way it's meant to be done. is_int() really checks for the dataTYPE and not the CONTENTS (of course the contents depend on the type, e.g. in an int you won't find a string). giving is_numeric() and the ctype functions strings as argument actually check for the CONTENTS (in different ways). is_int(1) => true is_int("1") => false is_numeric(1) => true is_numeric("1") => true I hope now everything is clear for everybody. Regards, B. Grupe P.S.: I think the general/help lists are more appropriate for these kind of problems before asking internals. P.P.S.: Sorry for potential spam, but I thought it is necessary to clear it up once and for all.
