1.方法構造
class Person
{//成員屬性
var $name;
var $age;
var $sex;
//構造方法
function __construct($name,$age,$sex)
{
$this->name=$name;
$this->age=$age;
$this->sex=$sex;
}
function say()
{
echo "我的名字:$this->name,我年齡是:$this->age,我的年齡是:$this->sex<Br>";
}
function eat()
{
}
function run()
{
}
function work()
{
}
function __destruct()
{
echo "$this->name.再見";
}
}
$p1=new Person("gaoyuan","25","男");
$p2=new Person("gao","250","男");
$p3=new Person("yuan","2500","女");
$p1->say();
$p2->say();
$p3->say();
2.封裝和提供可更改成員屬性接口
class Person
{
//成員屬性
private $name;
private $age;
private $sex;
private $phone;
//構造方法
function __construct($name,$age,$sex)
{
$this->name=$name;
$this->age=$age;
$this->sex=$sex;
}
//成員方法
function say()
{
echo "我的名字:$this->name,我年齡是:$this->age,我的年齡是:$this->sex<Br>";
}
//提供可以改變屬性的方法
function setAge()
{
if($age <0 || $age >150)
return;
$this->age=$age;
}
function getAge()
{
return $this->age-10;
}
private function eat()
{
}
private function run()
{
}
private function work()
{
}
function __destruct()
{
echo "$this->name.再見";
}
}
$p1=new Person("gaoyuan","25","男");
$p2=new Person("gao","250","男");
$p3=new Person("yuan","2500","女");
$p1->getage();
$p1->say();
$p2->say();
$p3->say();
