There are three ways to destroy PHP session

<?php
/* session的销毁 */
@header(&#39;content-type:text/html;charset=utf-8&#39;);
session_start();


$_SESSION[&#39;username&#39;]=&#39;test1&#39;;
echo &#39;session没销毁时：&#39;.$_SESSION[&#39;username&#39;];
echo "<br>";
//方法一
// $_SESSION['username']=null;
//方法二
//session_unset();
//session_destroy();
//方法三
$_SESSION=array();
echo 'session销毁后：'.$_SESSION['username'];

The above introduces the three methods of destroying PHP sessions, including the relevant contents. I hope it will be helpful to friends who are interested in PHP tutorials.
