PHP object is null after initialization

Question

I have the class file:

class Settings
{
public $siteName;
public $siteAddr;
public $dbUrl;
public $dbName;
public $dbPass;

public function __construct()
{
$siteName = 'Welcome';
$siteAddr = 'http://site.com';
$dbUrl = 'test';
$dbName = 'base';
$dbPass = '123';
}
}

Trying to use it in other file:

require_once('settings.php');
$cfg = new Settings();
var_dump($cfg); // <--- everywhere is null...

Why does it contain only nulls?

Instead of

$siteName = 'Welcome';

you need

$this->siteName = 'Welcome';

otherwise you just created variables in scope of your constructor, not initialized object members.

The variables you're using in your constructor are local scope variables. To refer to class fields use $this->fieldname.
