Should I somehow protect my $_FILE user input?
<p>I want to make my site hack-proof so this is why I do:</p>

<pre><code>Text: mysql_real_escape_string($myVar);
Number: (int)$myVar;
</code></pre>

<p>Should I use something similar to file array that is given by <code>$myVar = $_FILE['myFile'];</code> ?</p>
