What does "=>" mean in PHP?
<p>What does the <code>=&gt;</code> operator mean in the following code?</p>

<pre><code>foreach ($user_list as $user =&gt; $pass)
</code></pre>

<p>The code is a comment at PHP.net.
The user does not specify the value of <code>$user_list</code>, <code>$user</code> or $pass.
I normally see that <code>=&gt;</code> means equal or greater than.</p>

<p>However, I am not sure about its purpose here because it is not assigned.
I read the code as </p>

<ol>
<li>process a list of users in integers</li>
<li>such that the value of each user is equal or greater than password   </li>
</ol>

<p>The above does not make sense to me.</p>
