But that will also match 30,15,888,150,200, etc...

If you really want to use a regex for this, you'll need to anchor it like so:

$i =~ /^(0|5|8|15|20)$/;

Update: changed the square brackets to parens, thanks Hofmator...

Well, no ... $i =~ /[0|5|8|15|20]/;matches one character which is either 0, 1, 2, 5, 8 or |. And only if you correct the typo ;-)

What you can do is use parenthesis like this $i =~ /^(0|5|8|15|20)$/; but make sure you have the start and end of string assertions, otherwise you will match much more numbers.

Apart from that I think a hash would be a better solution as already mentioned elsewhere.

$i = 1;
print "found\n" if $i =~ /[0|5|8|15|20]/;
