What exactly does this PHP code do? system("php ./somescript.php $something >/dev/null &");
<p><code>system("php ./somescript.php $something &gt;/dev/null &amp;");</code></p>

<p>I'm new to PHP and I am deciphering someone else's code and can't figure out what this code is doing. I looked at the <code>system</code> documentation <a href="http://php.net/manual/en/function.system.php" rel="nofollow">here</a> so I understand that it will execute the PHP script in <code>somescript.php</code>, and that <code>$something</code> is a parameter passed to that script...but after that I'm lost.</p>

<p>Also, what part of the script does <code>$something</code> get passed to? How does it know what function in <code>somescript.php</code> to call first?</p>
