It's a lazy coding hack used to prevent a syntax error in the event that $cid or $hot are not defined. The 'foo' part of the string doesn't prevent the match as grep ignores it. That said, it could actually cause it to break if $dow just happens to be "foo" (or some substring of it).
A tidier solution is to instead use "$cid" or to first evaluate "$cid" and check it's defined.
