Hello,

A simple possibility could be to declare an array with all the values
that $a cannot take and use the in_array() function. Something like this:

$forbiddenValues = array(1,2,3,4,17,30);
if (in_array($a, $forbiddenValues ))
{
// some code
}

But it does not allow you to define something like "all values between 1
and 4".
