PHP cast from string to int error

Question

Hi when trying to cast from a string to int using int() i get the following error:

Call to undefined function int()

Why would this be?

inval() works just fine but i cannot use int() for some reason

Answer 1

Have you tried

$intVar = (int)$var;

If PHP is telling you that int() isn't a function, then it probably isn't.

Answer 2

There is no int function; you must use proper typecasting syntax for this:

$b = (int) $a;

Answer 3

function int($string) {
   return (int) $string;
}
