Why this doesn't work? [PHP]

[liam_d]

class video
{
    public function __construct($text)
    {
	$this->youtube($text, "[*]");
    }

    public function youtube($text, $code)
    {
        $html = preg_replace("#\[\*\]#", $text, $code);

        return $html;
    }
}  

$video_class = new video("HELLO");

echo $video_class;

Can someone explain to me why that gives this error:

Catchable fatal error: Object of class video could not be converted to string in /home/prxainf1/public_html/gamingonlinux.info/test.php on line 21

I'm sorry to be Captain Obvious, but "echo" is intended to output strings, not objects In your example variable $video_class is an object, so you can't just output it.

Are you familiar with object-oriented programming?

This will work:

class video
{
    protected $text;
    protected $code;

    public function __construct($text,$code="[*]")
    {
        $this->text = $text;
        $this->code = $code;
    }

    public function __toString()
    {
        $html = preg_replace("#\[\*\]#", $this->text, $this->code);

        return $html;
    }
}  

$video_class = new video("HELLO");

echo $video_class;

Or this should work

<?php
class video
{
    public function __construct()
    {
    }

    public function youtube($text, $code)
    {
        $html = preg_replace("#\[\*\]#", $text, $code);

        return $html;
    }
}  

$video_class = new video();
echo $video_class->youtube('HELLO', "[*]");
?>

Use var_dump to display objects
