PHP syntax question: global $argv, $argc;
<p>So I have a PHPUnit test, and found this code within a function.</p>

<pre><code>global $argv, $argc;
echo $argc;
print_r($argv);
</code></pre>

<p>I understand what these variables represent (arguments passed from the command line), but I've never seen this syntax before:<code>global $argv, $argc;</code></p>

<p>What specifically is going on here?</p>
