Re: How to find if a string is an integer?

Why don't you write your own test function since it's getting so hard to find one. All you have to do is check if the string only has number characters. I would say this is a simple task! Good luck, Rafael On Thu, 12 Jun 2003 13:13:28 -0700 (MST) "Alex Earl" <slide@duke-of-earl.com> wrote:

Jumping in a little late here, but what about is_numeric()? Haven't tried it, but the php manual for is_int says: Note: To test if a variable is a number or a numeric string (such as form input, which is always a string), you must use is_numeric(). The problem with is_numeric() is that something like "4e4" comes up as true, because it could be construed as a HEX value.
