Question

class Magic{
    public $a="i";
    public $b=array("a"=>"A","b"=>"B","c"=>"C");
    public $c=array(1,2,3);

    public function __get($v)
    {
     echo "<br/>get->$v";
     return $this->b[$v];
    }

    public function __set($var,$val)
    {
    echo "<br/>set->$var: $val,";
    $this->$var=$val;
    }
    }

    $m=new Magic();
    echo $m->a." , ".$m->b." ,".$m->c." ,";
    $m->c="CC";
    echo $m->a." , ".$m->b." ,".$m->c;

Output:i , Array ,Array ,i , Array ,CC

Now, I modify the visibility to protected for variable $b and $c.

Output: bci , B ,C ,c: CC,bci , B ,C

As far as I understand _get and_set is called for undefined var .So, when access modifier or visibility is set to protected why __get() is called !.

Can someone explain ….. I am not able to understand this.

Answer 1

From the manual

__set() is run when writing data to inaccessible properties.

__get() is utilized for reading data from inaccessible properties.

A protected / private property is considered inaccessible from an external scope.
