Hello, I'm trying to check for the occurrence of a string/value within another string. In this case:

$thestring = "13,130,213";
$thecheck = "13";

if ($thecheck =~ /$thestring/) { print "$thecheck is in $thestring"; }

Currently I get no output. I could for loop the $thestring splitting on the comma, however, I'd prefer not to do it. At the same time I don't want false positives to be returned either (in this example only 13 should be returned not 130 or 213). The actual value is not displayed only checked if the string/value is in the compare string. Yes, these are numbers, however I'm intentionally handling them as strings as numbers or letters can be in either string.

I'm most likely doing this wrong, but for the life of me, I can't figure out the right way. Can someone please enlighten me?
