PHP Session Usage

Session management, a very important part, let the parameters pass between the pages, this is a simple example, while learning to use, the effect as shown:

Main Page index.php code:

<?php
session_start();
$_SESSION['name']="zhang3";
echo "<a href='page2.php'>通过SESSION传递用户zhang3,显示欢迎信息</a>";
?>

Session_Start () begins the session, and each page must be invoked to use sessions.

page2.php Code:

<?php
session_start();
echo $_SESSION["name"]." 欢迎你！"."<a href='index.php'>返回</a>";
?>
