why this doesn't work? [PHP]

liam_d · 09-01-2010, 08:20 AM

PHP Code:

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

    public function youtube($text, $code)
    {
        $html = preg_replace("#\[\*\]#", $text, $code);
????: NamePros.com http://www.namepros.com/programming/675153-why-this-doesnt-work-php.html

        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:

PHP Code:

  class video

{

    protected $text;

    protected $code;

 
    public function __construct($text,$code="[*]")

    {

        $this->text = $text;

        $this->code = $code;

    }

 
    public function __toString()

????: NamePros.com http://www.namepros.com/showthread.php?t=675153
    {

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

 
        return $html;

    }

}  

 
$video_class = new video("HELLO");

 
echo $video_class;

Or this should work

PHP Code:

  <?php

class video

{

    public function __construct()

    {

    }

 
    public function youtube($text, $code)

????: NamePros.com http://www.namepros.com/showthread.php?t=675153
    {

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

 
        return $html;

    }

}  

 
$video_class = new video();

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

?>
