起风网声明一个类：car.class.php用于在类的公有方法中调用私有方法的返回值
<?php
class Car{
private $color;
private $type;
//构造方法为参数颜色和类型赋值
function __construct($color,$type){
$this->color=$color;
$this->type=$type;
}
//switch…case…语句取得post方法传递过来的值，一个case对应一个单选按钮的值
private function get_color(){
switch($this->color){
case ‘red’:
$mycolor=’红色’;
break;
case ‘white’:
$mycolor=’白色’;
break;
case ‘black’:
$mycolor=’黑色’;
break;
case ‘blue’:
$mycolor=’宝石蓝’;
break;
}
return $mycolor;
}
private function get_type(){
switch($this->type){
case ‘benz’:
$mytype=’奔驰’;
break;
case ‘horse’:
$mytype=’宝马’;
break;
case ‘audi’:
$mytype=’奥迪’;
break;
case ‘jieda’:
$mytype=’捷达’;
break;
}
return $mytype;
}
//公有方法调用私有方法，输出返回值！
function getinfo(){
echo “我的汽车是:”.$this->get_color().$this->get_type();
}
}
?>
创建HTML表单，通过提交可以输出我对于汽车的选择信息
