One. In this question that you asked :)

If you try to parse a string to an int this is what you get:
1. (int) "1234" => 1234
2. (int) "1234blah5678" => 1234
3. (int) "blah" => 0
4. (int) "blah1234" => 0

Well it will depend how you look at it.. and depending if you consider different syntax as a different case.
eg:


$x = 123;

$number = (int) $x;

$number = ((is_numeric($x)? (int) $x:0);
