    <p>I have written PDO classes with DB connection for a single website but what I actually need to use the same class across multiple websites. </p> <p><strong>The idea is that when I change something in the class the changes will reflect in all my website not just one but these 2 websites will still use 2 separate DBs</strong></p> <p>Could you please advice me on how to solve my problem or where should I start looking</p> <p>e.g.</p> <pre><code>core\ classes \ product.class.php Web_1 -databass.class.php for Web_1 using the core\classes\ Web_2 -databass.class.php for Web_2 using the core\classes\ </code></pre> <hr> <p>This is my part of my code</p> <p><strong>File dbConfig.php</strong></p> <pre><code>&lt;?php define('DB_TYPE', 'mysql'); define('USER_NAME', 'test'); define('USER_PASSWORD', '********'); define('HOSTNAME', 'localhost'); define('DB_NAME', 'test_db');?&gt; </code></pre> <p><strong>File databass.class.php</strong></p> <pre><code>&lt;?php include_once($_SERVER['DOCUMENT_ROOT'] . 'dbConfig.php'); class DatabasePDO { private static $_instance = array(); static function getInstance ($dbName = DB_NAME) { if (! array_key_exists($dbName, self::$_instance)) { $dsn = DB_TYPE . ":host=" . HOSTNAME . ";dbname=" . $dbName; try { self::$_instance[$dbName] = new PDO($dsn, USER_NAME, USER_PASSWORD); self::$_instance[$dbName]-&gt;setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); } catch (PDOException $e) { echo "echo "Error!: " . $e-&gt;getMessage(); die(); } } return self::$_instance[$dbName]; } }?&gt; </code></pre> <p><strong>File product.class.php</strong></p> <pre><code>&lt;?php require_once "databass.class.php"; class products_CLS { private $pid = null; private $title = ''; private static $dbConn = null; public function __construct () { self::initializeConnection(); } private static function initializeConnection () { if (is_null(self::$dbConn)) { self::$dbConn = DatabasePDO::getInstance(); } } /** * @return the $productid */ public function getProductId() { return $this-&gt;pid; } /** * @return the $producttitle */ public function getProductTitle() { return $this-&gt;title; } }?&gt; </code></pre>

    2. COproduct.class.php uses require_once "databass.class.php"; which means this class is only used on this DB but what should I do if I want to use the same class on different website.I need to copy the class and put it in another fodler but I want to keep one core class which is used on multi websites

    3. COYou will probably want to eliminate the singleton and use parameterized configuration instead of constants. This will allow you to create multiple connection objects with different configs using the same class.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
