This article mainly introduces simple examples of PHP initialization objects and destructors. Friends who need it can come and refer to it. I hope it will be helpful to everyone

Code As follows:

<?php
 /**********************************************
 *  construct  对象初始化函数使用
 *  destruct      析构函数的使用
 *  $this         关键字的使用（$this关键字是用来访问当前对象中的对象
属性
和对象 *        方法的
系统变量
）
 * 
 **********************************************/
 header("Content-Type:text/html;charset=UTF-8");
 class mypc{
  public $name;
  public $type;
  function construct($name=&#39;&#39;,$type=&#39;&#39;){ //初始化对象，将初始化值放在括号内
   $this->name=$name;
   $this->type=$type;
  }
  function vod(){
   
return
 $this->name.$this->type.&#39;播放电影&#39;;
  }
  function game(){
   return $this->name.$this->type.&#39;玩游戏&#39;;
  }
  /************************
  * 当对象内部的操作执行完毕的时候，
  * destruct()被调用，
  * 然后对象所使用的内存被释放出来。规则：后进先出
  **************************/
  function destruct(){
   echo "<br>==============".$this->name;
  }
 }
 $pc1 = new mypc(&#39;家用电脑&#39;,&#39;台式机&#39;);
 echo $pc1->vod()."<br>";
 //当$pc1=null;的时候是当前实例操作完成后直接释放出对象
 $pic2 = new mypc(&#39;公司电脑&#39;,&#39;笔记本&#39;);
 echo $pic2->game();
