Not quite. That method will massage both values to the same type for the comparison. Whoever shot it down said they both go to int. If that's the case, if ($val == (int)$val) is more like saying if ((int)$val === (int)$val) What I suggested converts the string to an int, the resulting int back to a string, then does a type-specific comparison to the original string value.
