DB Connection using Zend_Db

In this article, we will connect to DB and execute SQL using Zend_DB. You can download the source code of this article from here.

Create the file application/config.ini with the following content.
Please modify database.params.* properly.

[staging]
database.adapter         = pdo_mysql
database.params.host     = localhost
database.params.username = db_user
database.params.password = db_password
database.params.dbname   = db_name

In this article, we will use the following sql.

CREATE TABLE profiles
(
    id integer AUTO_INCREMENT NOT NULL PRIMARY KEY,
    user_id integer         NOT NULL,
    first_name varchar(100) NOT NULL,
    last_name varchar(100)  NOT NULL,
    email varchar(200)      NOT NULL,
    url varchar(200)        NOT NULL
);
 
INSERT INTO profiles (user_id, first_name, last_name, email, url)
    VALUES (1, 'Myfirstname', 'Mylastname', 'my@emailaddress',
        'http://myurl/my/page');

Create the file application/constorllers/IndexController.php with the following content.

<?php
require_once 'Zend/Controller/Action.php';
require_once 'Zend/Db.php';
require_once 'Zend/Config/Ini.php';
 
class IndexController extends Zend_Controller_Action
{
    protected function getDbAdapter()
    {
        $config = new Zend_Config_Ini(CONFIG_PATH, 'staging');
        $dbAdapter = Zend_Db::factory($config->database);
        return $dbAdapter;
    }
 
    public function indexAction()
    {
        $db = $this->getDbAdapter();
        $sql =<<<EOSQL
<|!REG3XP0!>SELECT
    id
    ,user_id
    ,first_name
    ,last_name
    ,email
    ,url
FROM
    profiles
WHERE
    user_id = :user_id|>
EOSQL;
        $params = array('user_id' => 1);
 
        $db->setFetchMode(Zend_Db::FETCH_ASSOC);
        $row = $db->fetchRow($sql, $params);
        if ($row)
        {
            $this->view->profile = $row;
        }
    }
}

Create the file application/views/scripts/index/index.phtml with the following content.

 
<h1><?= $this->translate('Your Profile') ?></h1>
 
<?php if (!$this->profile) : ?>
<span><?= $this->translate('No Profile Found') ?></span>
<?php else : ?>
<dl>
<?php foreach($this->profile as $key => $value) : ?>
<dt><?= $this->translate($key) ?></dt>
<dd><?= $this->escape($value) ?></dd>
 
<?php endforeach; ?>
</dl>
 
<?php endif; ?>

Let's access the Web Server and check the screen.
