mysql connections

how do I make a permanent connection to mysql database and what is difference between mysql_connect() and permanent one? If I make connections in one file and redirect it to another file do I keep connection (permanent / standard)? Do I lose connection only when I type mysql_close (permanent/ standard)? if I select different database between the php program do I need to do something extra along mysql_select_db("dbname",$link)? If I opened db in another php file, where do I get the $link variable from = mysql_connect (when selecting another database)?
