How to Connect login form to Mysql Db connection Pls..tell me

Answer 1

Specify variables for username and password and connect with the MySQL database using the mysql_connect() function. The username “root” does not require a password by default.
Specify the server parameter of the mysql_connect() method as localhost:3306.
$username='root';
$password='';
$connection = mysql_connect('localhost:3306', $username, $password);
If a connection does not get established output the error message using the mysql_error() function.
if (!$connection) {
$e = mysql_error($connection);
echo "Error in connecting to MySQL Database.".$e;
}
