Very strange error by query!

[Velocd]

This isn't really an error, but it bugs. In showthread.php, I am running this query within the file for one of my hacks:

PHP Code:

$threads = $DB_site->query("SELECT title,threadid FROM thread WHERE forumid=$thread[forumid]"); 


For some reason, in showthread.php, at any thread, I am seeing this:

Resource id #X

X changes depending on thread, such as in one thread it says:

Resource id #24

Any idea why a query is doing this? I've commented out the rest of my hack to just this query and it's defiantly the cause of the problem.
