title: php multiple image uploader
body: <p>For the sake of God can someone help me make the below script to upload multiple images(5). I'm stuck at this for days with no luck. I have no idea how to make it upload five images. Pleeeease help me. I tried putting five input file fields and giving them a name like <code>name="file[]"</code> but that doesn't seem to be working. While I upload a photo I see a error saying please select a photo even if there is a file.</p>
