Abstract database models with PDO MySQL (Zend Framework)

Zend Framework allows you to create models which extendA�Zend_Db_Table_Abstract. The shelf life of prevacid. snippets below demonstrate abstract database models.

Modify application.ini for your database connection.

resources.db.adapter = PDO_MYSQL
resources.db.params.host = localhost
resources.db.params.username = databaseuser
resources.db.params.password = databasepass
resources.db.params.dbname = databasename

Example model


class Application_Model_Example extends Zend_Db_Table_Abstract

    protected $_name = 'example'; // Use the example table

    public function fetchAllExamples(){
	// Will return all rows in the example table
	return $this->fetchAll();

    public function getExample($exampleId){
	// Will return an example row with a given id
	$exampleSelect = $this->select()->where('exampleId= ?', $exampleId);
	return $this->_fetch($exampleSelect);



The framework will automatically initiate the database connection and will allow you to use the Application_Model_Example class to perform database operations on the example table.

    Thanks very much for this example, I’ve finally got my head around how models work using this great example. I’ve been trying to create a User model inside the my User module:

    Only problem i came across was using a model inside a module i didn’t need the Application_ bit in the class names, so i had User_Model_User.

    To get the model to load i had to make a Bootstrap.php inside the User Module folder :

    Also i linked the controller to the model like so :
    $user = new User_Model_User();
    $this->view->user = $user->getUser($usersessionid);

    Also to display the information in a view i used:

    user as $key => $user) : ?>

    Thanks again, and i hope the above comments are helpful to someone :)
