Question

Why does this abstract class not work and output nothing?

<?php
abstract class Con {
    function __construct($name);
    }
}
class Shop extends Con {
    function __construct($name) {
        $this->shopname = $name;
    }
    function write() {
        echo $this->shopname;
    }
    function outputdate() {
        echo ' ' . date('Y');
    }
    function __destruct() {
        $this->outputdate();
    }
}

Answer 1

You cannot define some class in other class body. Instead, you must use PHP OOP features to extend one class from another.

class Shop extends Con{
...code goes here....
}
$shop = new Shop('shopname');
$shop->write();
