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

[Ant�nio Rafael Paiva]

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,

The problem with is_numeric() is that something like 
"4e4" comes up as
true, because it could be construed as a HEX value.
