1、老规矩，先定义类，然后写构造方法。<?php class Person{

public $sex;public $age;public $name; function __construct($sex,$age,$name{$this->sex=$sex;$this->age=$age;$this->name=$name;

echo "I am".$this->age.",I am a".$this->sex.",my name is".$this->name;}

2、接着new一个Person.如下写：$p1=new Person('girl',13,'JILLY');

3、补上括号}.保存。运行后，结果如图：
