PHP is going to free the data when your script ends, so most common uses of MySQL don't even need mysql_free_result, as your page doesn't do anything after it's done with MySQL anyway. In some scripts, you are "done" with a large result set, and can gain some performance by releasing all the resources tied to that result set. The argument to mysql_free_result is a result resource, and it frees ALL the records, as you call it, and any other resources that result set is using. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
