title: Does $_FILES['userfile']['name'] Return "FileName.ext" or just "FileName"
body: <p>I'm using this to check and see how long the name of an upload is by saving the name as a string and using <code>strlen()</code> to get the length of the name. I need to know if <code>$_FILES['userfile']['name']</code> returns the extension as part of the string name so I can strip it off before counting the string length.</p>
