"mysql_connect establishes a connection for the duration of the script that access the db. Once the script has finished executing it closes the connection. The only time you need to close the connection manually is if you jump out of the script for any reason. "

What does he mean by jump out?
I used header redirection, is this "jump out", but after header redirection, I always added exit;,
does it mean that I need to close the connection before I use header redirection?
Thanks!
