<?php//在php中创建类/*** Created by PhpStorm.* User: zsgjs038* Date: 2015/9/1* Time: 13:08*/class Hello{public function  sayHello(){print_r("method is pass");}}//创建一个类class DeskTop{public function  work(){echo "other class";}}

<?php//类和命名空间介绍/*** Created by PhpStorm.* User: zsgjs038* Date: 2015/9/1* Time: 13:08*///在同一文件夹下require_once 'Hello.php';$h = new Hello();$h->sayHello();echo '<br/>';$d=new DeskTop();$d->work();echo '<br/>';//所有文件和文件夹都在classes04文件夹下require_once 'space01/Zhh.php';require_once 'space02/Zhh.php';//命名空间myzhh1下的Zhh类$z1=new \myzhh1\Zhh();$z1->myDemo01();echo '<br/>';//命名空间myzhh2下的Zhh类$zhh1=new \myzhh2\Zhh();$zhh1->myDemo01();echo '<br/>';//调用嗲参数的构造方法require_once 'Man.php';$m = new Man("zhh",20);echo $m->getName();echo $m->getAge();

<?php//构造方法：/*** Created by PhpStorm.* User: zsgjs038* Date: 2015/9/1* Time: 13:47*/class Man {//    构造方法，固定写法//    public function  __construct(){//        print_r("gou zao fang fa");//    }private $name;private $age;/*** @param $name 名字* @param $age  年龄*///  构造方法名称都一样所以，只能写一个public function  __construct($name,$age){$this->name = $name;$this->age = $age;}public function getName(){return $this->name;}public function getAge(){return $this->age;}}
