Question

I have set constants for database in connect.php.

connect.php

define('DB_HOST','localhost');
define('DB_NAME','dbname');
define('DB_USER','dbuser');
define('DB_PASSWORD','dbpass');

Here is the Database Class

require("connect.php");
    class Database {

    private $connect;

    function opendb() {
    $this->connect = new PDO(DB_NAME, DB_USER, DB_PASSWORD);

    }


    function closedb() {
    $this->connect =  null; //close connection

    }

    }

I get this error when i load the page that accesses the database class.

Fatal error: Uncaught exception 'PDOException' with message 'invalid data source name'

what did i do wrong?

You need to use this –

$this->connect = new PDO('mysql:host=' . DB_HOST . ';dbname=' . DB_NAME, DB_USER, DB_PASSWORD);
