Your pattern is trying to recursively match patterns, which is a grey area
according to the php manual at least. May I ask why you're using pattern
matching for this? You could just use:
$text="[download: 12,20,28]";
$id=explode(",", substr($text, 11, -1));
That would give you an array of 12, 20, 28, and without pattern matching...
