For my money, `is_numeric()` does just what I want.


The thing is, is_numeric() will not check if a string is a valid int,
but any valid number, including a float.

For something like this, wouldn't a regex be better?

if(preg_match('/^\-?\d+$/', $string))
echo int

I'm late in on this thread so apologies if I have missed something here
.. but wouldn't is_int() do what the OP wants?

Nope, because the OP wants to test if a variable, that is a string, could be converted to an integer. Not if a variable is an integer.
