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

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.
