Cookies are available on the client-side, so they can be seen from the browser.

 
On the other hand, session data is stored on the server, and never sent to the client (except you write some code to do just that, of course).

To dump the content of a variable, like <code>$_SESSION</code>, you can use the <a href="http://fr2.php.net/var_dump" rel="noreferrer"><code>var_dump()</code></a> function.
 On a development server, you can install the <a href="http://xdebug.org/" rel="noreferrer">Xdebug</a> extension to enhance its output greatly (and lots of other debugging-related things, btw).

If you don't want to pollute the HTML of your page, you could install the <a href="http://www.firephp.org/" rel="noreferrer">FirePHP</a> extension to FireBug, and use the corresponding PHP library to send data (like dump of variables) to it.
 
This would allow your variables, like <code>$_SESSION</code>, to be displayed in firebug's console.

PHP session variables are stored on the server and are inaccessible to the client.

blocks|key|2098897|text|不是的。会话数据是服务器端的，而cookie是客户端的。会话cookie包含会话标识符，服务器(即:+PHP)使用它来检索正确的会话数据。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2098898|如果不远程访问服务器或使用脚本(驻留在服务器上)，则无法查看会话数据。|2098899|这就是为什么建议将“敏感”信息存储在session中，而不是cookies中，因为它不容易被查阅/更改。|2098900|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

No. Session data is server-side, while cookies are client-side. The session cookie contains the session identifier, which the server (i.e.: PHP) uses to retrieve the proper session data.

It is not possible to view session data without remote access to the server, or using a script (that resides on the server).

This is why it is recommended to store "sensitive" information in session instead of cookies, because it cannot be consulted/altered easily.

blocks|key|2098860|text|不是的。会话变量存储在服务器上。在火狐中唯一可见的是会话ID，存储在会话cookie中(例如PHP_SESS_ID=randomgarbage)。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|2098861|您必须显式地编写一个脚本来转储会话变量，就像下面这样简单：|2098862|dumpsession.php：|2098863|<pre>

No. Session variables are stored on the server. The only thing that would be visible in Firefox is the ID of the session, stored in the session cookie (e.g. <code>PHP_SESS_ID=randomgarbage</code>).

You'd have to explicitly write a script that would dump out the session variables, something as simple as:

dumpsession.php:

<pre><code>&lt;pre&gt;
&lt;?php
 var_dump($_SESSION);
</code></pre>

I had this simple script that shows the $_SESSION variables.

<pre><code> &lt;?php
error_reporting(E_ALL);
session_start();
if (isset($_POST['session'])) {
 $session = eval("return {$_POST['session']};");
 if (is_array($session)) {
 $_SESSION = $session;
 header("Location: {$_SERVER['PHP_SELF']}?saved");
 }
 else {
 header("Location: {$_SERVER['PHP_SELF']}?error");
 }
}

$session = htmlentities(var_export($_SESSION, true));
?&gt;
&lt;!DOCTYPE html&gt;
&lt;html lang="en-US"&gt;
 &lt;head&gt;
 &lt;meta charset="UTF-8"&gt;

 .saved, .error { border: 1px solid #509151; background: #DDF0DD; padding: 2px; }
 .error { border-color: #915050; background: #F0DDDD; }
 &lt;/style&gt;
 &lt;/head&gt;
 &lt;body&gt;
 &lt;h1&gt;Session Variable Management&lt;/h1&gt;
&lt;?php if (isset($_GET['saved'])) { ?&gt;
 &lt;p class="saved"&gt;The session was saved successfully.&lt;/p&gt;
&lt;?php } else if (isset($_GET['error'])) { ?&gt;
 &lt;p class="error"&gt;The session variable did not parse correctly.&lt;/p&gt;
&lt;?php } ?&gt;
 &lt;form method="post"&gt;
 &lt;textarea name="session" rows="&lt;?php echo count(preg_split("/\n|\r/", $session)); ?&gt;"&gt;&lt;?php echo $session; ?&gt;&lt;/textarea&gt;
 &lt;input type="submit" value="Update Session"&gt;
 &lt;/form&gt;
 &lt;/body&gt;
&lt;/html&gt;
</code></pre>

Install it on a test server, name it "sess.php" or something like that, and it shows the current session. 
DO NOT LEAVE IT ON A PRODUCTION SERVER !!!

Not sure if this belongs here or at webapps... please move if appropriate.

I don't even know if such a thing is possible, but is there an extension or add-on for either Firefox or Chrome that would let me view all my PHP session variables the way there are extensions that let you view cookies?

不确定这是属于这里还是属于webapps...请在适当的情况下移动。我甚至不知道这样的事情是否可能，但是Firefox或Chrome是否有一个扩展或附加组件，可以让我像查看cookie的扩展一样查看所有的PHP会话变量？
