    function showAd(){
       echo "2016新款女装";
    }
    function showCategory(){
        echo "女装";
    }
}

namespace IMooc;

class MaleUserStrategy implements UserStrategy{
    function showAd(){
        echo "surface pro5";
    }
    function showCategory(){
        echo "电子产品";
    }
}

class Page{
    protected $strategy;
    function index(){
        $this->strategy->showAd();
        echo "\n";
        $this->strategy->showCategory();
    }
    function setStrategy(\IMooc\UserStrategy $strategy){
        $this->strategy = $strategy;
    }
}
$page = new Page;
if(isset($_GET['famale'])){
    $strategy = new IMooc\FamaleUserStrategy();
}else{
    $strategy = new IMooc\MaleUserStrategy();
}
$page->setStrategy($strategy);
$page->index();
