Pass an object as parameter in PHP
<p>In Java, I can pass an object straight in parameter </p>

<pre><code>public int foo (Bar bar)
{
    ... call the methods from Bar class
}
</code></pre>

<p>So how can I do same thing with PHP. Thanks
This is my code:</p>

<pre><code>class Photo
{
    private $id, $name, $description;
    public function Photo($id, $name, $description)
    {
        $this-&gt;id = $id;
        $this-&gt;name = $name;
        $this-&gt;description = $description;
    }
}
class Photos
{
    private $id = 0;
    private $photos = array();

    private function add(Photo $photo)
    {
        array_push($this-&gt;photos, $photo);
    }
    public function addPhoto($name, $description)
    {
        add(new Photo(++$this-&gt;id, $name, $description));
    }
}
$photos = new Photos();
$photos-&gt;addPhoto('a', 'fsdfasd');
var_dump($photos); // blank
</code></pre>

<p>If I change the  function add</p>

<pre><code>function add($name, $description)
{
    array_push($this-&gt;photos, new Photo(++$this-&gt;id, $name, $description));
}
</code></pre>

<p>It works pefectly. So What is wrong ?</p>
