exiting a loop early

i saw mist ask for this once but couldn't find the thread :(

anyhoo i have a loop but i want to exit it early as the query it's using is used for a few more things other than this loop.

i.e. table = 20 rows, loop = 4 rows

not sure about the best way to explain it but if someone could tell me how to do this i'd be eternally grateful :)

In a while(), for() or foreach() loop you can use break; to break out of it. Pseudo-code:

PHP Code:


		
			
$results = $DB_site->query("my query here");

while ($r = $DB_site->fetch_array($results))

{

    // do something or another



    // then when we get to the exit condition...

    if ($r['rowid'] == 4)

    {

        break;

    }

}
