Looks like you have some extra spaces in there that'll mess it up. The '?'
for example, is only applying to the space before it.
You want
preg_match("|$start(.*?)$end |i", $contents, $text);
Note that this will only return one match when there could be more,
depending upon your string. If you want all of them, use preg_match_all().
