SID在哪里？ [英] Where is SID?

问题描述

好吧，我会承认自己做错了（使用session_register（）），所以我要求b $ b试图纠正我的方式，但是......


我的脚本以

<？php

session_start（）;

？>


在我的页面正文中有如下链接：


< a href =" targetUrl.php？< php print SID ; ？>">目标文字< / a>


问题：SID是一个空字符串。我甚至尝试了

echo" SID：" 。 SID。 ''< br />'';


和SID作为一个空字符串回应。为什么？


---迈克尔

OK, I''ll admit I''ve been doing it wrong (using session_register()), so I''m
trying to correct my ways, but...

My script starts with
<?php
session_start();
?>

In the body of my page a link as follows:

<a href="targetUrl.php?<php print SID; ?>">Target text</a>

Problem: SID is an empty string. I even tried
echo "SID: " . SID . ''<br />'';

and SID echoes as an empty string. Why?

几个星期前我问过这个问题 - 你可能可以搜索

线程，虽然没有答案特别有启发性。它显示SID常量仅在某些情况下设置为
。我从来没有确定过b $ b确实能够解决它们的问题。使用session_id（）函数获取

会话ID - 这似乎是正确可靠的方法。

I asked this a few weeks back - you might be able to do a search for the
thread, although none of the answers were especially illuminating. It
appears the SID constant is only set under certain circumstances. I never
did work out what they were. Use the session_id() function to get the
session ID - that appears to be the correct and reliable way to do it.
