PHP Magic Methods

Explain the Magic Method in Detail

The function names __construct(), __destruct(), __call(), __callStatic(), __get(), __set(), __isset(), __unset(), __sleep(), __wakeup(), __toString(), __invoke(), __set_state() and __clone() are magical in PHP classes. You cannot have functions with these names in any of your classes unless you want the magic functionality associated with them

/** class to test magic method i.e sleep and wakeup **/
class magicmethod
{
    public $name1 = 'Hello';
    function __wakeup()    {  
        echo "__wakeup funx called <br />";
        echo $this->name1;
    }
    function __sleep(){  
        echo "__sleep funx called <br />";
        $this->name1 ='Arun kumar';
        return array('name1');
    }
}
$obj = new magicmethod();
$objString = serialize($obj);
echo $objString;
echo "<br>"    ;
unserialize($objString);?>


//output

__sleep funx called
O:11:"magicmethod":1:{s:5:"name1";s:10:"Arun kumar";}
__wakeup funx called
Arun kumar
