PHP Upload Multiple Files

HTML5 and PHP allows multiple files upload using single Input element. Most tutorial for uploading multiple files never deals with Internet Explorer due to its lack for HTML5 support. However, there is a workaround thanks to Raymond Camden.
Adding multiple="multiple" in the file input allows you to select more than one file simply by pressing Ctrl simultaneously, this fails in IE as it does not support HTML5. We can show additional file upload input specially for IE and browsers which does not support "multiple" file uploads using small javascript. I created PHP Upload multiple files demo for this tutorial.
