The Better Way to Unset Variables in PHP

Don’t know why, but most of times I see the PHP unset() multilined with a only one parameter!?


But as you can see from the PHP doc page of unset() this method takes optional parameter count.

void unset(mixed $var [, mixed $var [, mixed $...]])

So perhaps a better solution can be:

unset($var1, $var2, $var3);

It’s at least single lined!

Which Model Should Contain That Method?

Let’s say you have two models – each one modeling a database table – Users & Article. Here there’s nothing to deal with Zend Framwork, but you can think of them as typical models in a ZF application.

What happens if you have to write a getUserArticles method? Where would you put it? Whether this will be the User model or the Article model?Where?

Although technically you can put it in both models my advice is to look at the SQL query. If the FROM clause is containing the user table – than put the method in the User model, but here you’d have something like:

SELECT * FROM Article WHERE user_id = 1

I’d prefer to place it in the Article model!

Setting Up Global Cache in Zend Framework

In a large scale web application, especially based on Zend Framework, there are lot’s of components that support built in cache support. Such are Zend_Db, Zend_Translate, Zend_Date, etc. Also you may need cache support wherever in the app, so my advice is to setup a cache instance in the “beginning”, into the bootstrap.php or even better – into a front controller plugin, and to store it into the Zend_Registry. Thus you’ve to change only the lifetime for specific needs:

class CacheInit extends Zend_Controller_Plugin_Abstract
    public function __construct()
        $frontendOptions = array(
            'automatic_serialization' => true,
            'lifetime' => 60
        $backendOptions  = array(
            'cache_dir' => realpath(APPLICATION_PATH . '/../cache')
        $cache = Zend_Cache::factory('Core',
        Zend_Registry::set('cache', $cache);

Than add it as a front controller plugin:

// cache plugin
$frontController->registerPlugin(new CacheInit());

Zend_Mail with GMail

Zend_Mail and GMail
You know how to setup Zend_Mail with SMTP, but you don’t know how to set it up with GMail! Here’s how to do it. Just follow the instructions 😉

$mailTransport = new Zend_Mail_Transport_Smtp('smtp.gmail.com', array(
    'auth'     => 'login',
    'username' => 'xxxxxx@gmail.com',
    'password' => 'passxxxxx',
    'port'     => '587',
    'ssl'      => 'tls',
