PHP Protected variables don't work for me

i'm having trouble with protected variables in PHP. Why doesn't work this code? It keeps showing me error 500. Here's the code:

<?php
class A
{
    protected $variable;
}

class B extends A
{
    $this->variable = 'A';
}
?>

<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>Document</title>
    </head>
    <body>
        <!-- Code -->
    </body>
</html>

Thanks

Solution

  • You can't put instructions like attributions at body of class. Only members definitions are allow. Put the $this->variable = 'A'; inside a method.

    Change:

    class B extends A
{
    $this->variable = 'A';
}

    To:

    class B extends A
{
    public function __construct(){
        $this->variable = 'A';
    }
}
