Problem with derived class


atitthaker

Recommended Posts

I have the code as given below:
<?php
class ABC {
    function printValue()
    {
        print("This value shall be printed" . $this->x);
    }
}
class BCD extends ABC {
    private $x=10;
}

$bcd=new BCD;
$bcd->printValue();

?>

But when I try to access printValue function from the paren class it gives me error...

[color=red]Fatal error: Cannot access private property BCD::$x in /var/www/html/trainingweb/modules/test/TestAtitProblem.php on line 5[/color]

As the public method of ABC would be extended to BCD, it shall have access to its own member.

Plz help...

When referring to $this->x in ABC the x variable has to be local to that class, in your example it is not.  x is local to BCD since it is declared as private.

 

To fix this, change private $x=10; to public or protected (as mentioned above)
