If someone can help me fix this , i will be thankful .

Answer 1

You are calling

mysql_select_db ( "moviesite");

But that is not part of PDO, it is part of MySQL.

You should be doing:

$DB_HOST = "";
$DB_NAME = "";
$DB_PASS = "";
$DB_PORT = 3306;
$DB_USER = "";

$dsn = "mysql:host=" . $DB_HOST . ";port=" . $DB_PORT . ";dbname=" . $DB_NAME . ";charset=utf8";

$db_connection = new PDO($dsn, $DB_USER, $DB_PASS);
