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

<&#63;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");
&#63;>
Copy after login

希望本文所述对大家的php程序设计有所帮助。
