[PHP] Casting nulls

[Carl Furst]

IF $int is null and I have a test

If($int  1) {
//do some foobar
}

will $int be evaluated as a zero? IF I cast (int) $int.. will that turn a
null $int into a zero??

Documentation aint too clear.

Thanks,

Carl.

In the time you've waited for an answer so far, you could have made
yourself a 3 line script to find out.

No idea what you're doing here, but you may want to look into the isset()
and/or empty() functions for identifying NULLs.

If I understood the question wouldn't this work???
if (!is_null($int)  $int  1)
{
   // do some foobar
}
