Dude that's major wrong your "if" is true for any numbers, because first:
$a >= 1
will always be true if you have a positiv number above 1. Second:
$a <= 4
any negative number including the 1 and 0 that you didn't catch with the
first rule.
The condition
$a == 17 || $a ==30
will never be reached, since they are already covered by:
$a >= 1
I think what you meant is:
if(($a >= 1 && $a <= 4) || $a == 17 || $a ==30)
right:-) Very important the brackets for condition "$a >= 1 && $a <= 4"
