Generally, you will close it when you know it will no longer be need so, you might do on a page:

[code]
<?php
$conn = mysql_connect(.....);

$conn = mysql_query($sql....);
//Use the database again
$x = getArticles($conn);

//Now we'll output html, no need for mysql
mysql_close($conn);

renderHtml($x....);
?>[/code]

You actually don't even need to close it most of the time as the link to the server will be closed as soon as the execution of the script ends. You only need to close it with mysql_close() if you have a specific reason to do so.

I don't close my connection.  The script close automaticly upon exit anyway.
And I used pconnect (persistent connection) instead of connect.

Personally, I don't see any security issue with that.

You'll only want to use mysql_close when using mysql_pconnect. As persistant connections will not close themselves, hens perisistant connections. However non-persistant connects wont need thier connection closed manually as they exit automatically once the script has been executed.
