php查看当前Session的ID实例，当前sessionid实例
本文实例讲述了php查看当前Session的ID的方法。分享给大家供大家参考。具体如下：
有两种方法可以得到用户的session id，第一是使用session_id()函数，另外一种是使用内置的常量SID获得，SID包含了session id和session值
<?php
session_start();
print("<html><b>");
$sid = session_id();
print("Session ID returned by session_id(): ".$sid."\n");
$sid = SID;
print("Session ID returned by SID: ".$sid."\n");
$mysite = $_SESSION["mysite"];
print("Value of mysite has been retrieved: ".$mysite."\n");
print("</b></html>\n");
?>希望本文所述对大家的php程序设计有所帮助。
