Is there any way to tell what type a variable is? My problem is this:
I query a db table for a primary key that is an integer. If the key exists
I return it,
otherwise I return false. Then I can do some like this:
$key = getKey("bob");
//if false was not returned
if ($key) {
//do stuff
}
But what happens if I get back a key of 0, since 0 in php is equivalent to
false? Is there any way to check whether
$key came back as an int or a bool?
Thanks

Oops, make that the last _four_ points :-)
