I'm creating a form where the data will be sent to a database at my server. My question is about the line of code below:

<?php
// Connect to MySQL
mysql_connect("my_server", "my_username", "my_password")
etc,
etc,
etc,
?>

My concern is about the line that asks me to enter my server, username and password.

Can't everyone see that? Am I giving everyone access to my server?

Forgive me for my ignorance.

Thanks.
