介绍PHP5的给类型函数应用

<?php
class cd {
	public $artist;
	public $title;
	protected $tracks;
	private $disk_id;
}

// Instantiate an object of class 'cd'.
$mydisk = new cd();

// Now update the artist's name
$mydisk->artist = 'The Child Song Singers';

// Now try to update the protected or private values.
// This will cause a fatal error:
$mydisk->tracks = array('Wheels on the Bus', 'Mary had a Little Lamb');
?>
