private $type;
function MyPc($name="",$type) {
$this->name = $name;
$this->type=$type;
}
function vod() {
return $this->name.$this->type."放电影";
}
/*
function __get($name) {
return $this->name."====";
}
function __set($na,$n) {
return $this->$na=$n;
}
*/
function __get($type) {
return $this->type."++++";
}
function __set($type,$tv) {

}
$pc1 = new MyPc("家用电脑","台式");
$pc1->name="aaaa";
$pc1->type="bbbb";
echo $pc1->name."<br>";
