HTML5 Image upload with javascript and php

JavaScript
1

I want to multi-upload images to a database using javascript and php (html5), but I have problem with it, my code is just uploading one image, which is the latest photo selected and not all. How can fix this problem and what do I have to do?

I use developer mozilla html5: Here

You can test my code by selecting multi images and clicking on button Upload Image to see the result.

DEMO FROM MY FULL CODDE

My js code:


function doClick() {
    var el = document.getElementById("fileElem");
    if (el) {
        el.click();
    }
}

function handleFiles(files) {
    var d = document.getElementById("fileList");
    if (!files.length) {
        d.innerHTML = "<p>No files selected!</p>";
    } else {
        var list = document.createElement("ul");
        d.appendChild(list);
        for (var i = 0; i < files.length; i++) {
            var li = document.createElement("li");
            list.appendChild(li);

            var img = document.createElement("img");
            img.src = window.URL.createObjectURL(files[i]);;
            img.height = 60;
            img.onload = function () {
                window.URL.revokeObjectURL(this.src);
            }
            li.appendChild(img);

            var info = document.createElement("span");
            info.innerHTML = files[i].name + ": " + files[i].size + " bytes";
            li.appendChild(info);
        }
    }
}

My php code:


<?php
  foreach ($_FILES[ 'userfile'] as $key=>$value{
      echo '<pre>';
      print_r($value);
  }
?>

My html code:


<html>

        <title>file input click() demo</title>
        <script type="text/javascript" src="html5java.js"></script>
