Answer 1

Looks like your PHP is correct.

On your device use HTTP POST request with MultipartEntity data type. Read more here

EDIT

Example from my link:

You will have to download additional libraries to get MultipartEntity running!

1) Download httpcomponents-client-4.1.zip from http://james.apache.org/download.cgi#Apache_Mime4J and add apache-mime4j-0.6.1.jar to your project.

2) Download httpcomponents-client-4.1-bin.zip from http://hc.apache.org/downloads.cgi and add httpclient-4.1.jar, httpcore-4.1.jar and httpmime-4.1.jar to your project.

3) Use the example code below.

    private DefaultHttpClient mHttpClient;


    public ServerCommunication() {
        HttpParams params = new BasicHttpParams();
        params.setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);
        mHttpClient = new DefaultHttpClient(params);
    }


    public void uploadUserPhoto(File image1, File image2, File image3) {

        try {

            HttpPost httppost = new HttpPost("some url");

            MultipartEntity multipartEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);  
            multipartEntity.addPart("Title", new StringBody("Title"));
            multipartEntity.addPart("Nick", new StringBody("Nick"));
            multipartEntity.addPart("Email", new StringBody("Email"));
            multipartEntity.addPart("Description", new StringBody(Settings.SHARE.TEXT));
            multipartEntity.addPart("file1", new FileBody(image1));
            multipartEntity.addPart("file2", new FileBody(image2));
            multipartEntity.addPart("file3", new FileBody(image3));
            httppost.setEntity(multipartEntity);

            mHttpClient.execute(httppost, new PhotoUploadResponseHandler());

        } catch (Exception e) {
            Log.e(ServerCommunication.class.getName(), e.getLocalizedMessage(), e);
        }
    }

    private class PhotoUploadResponseHandler implements ResponseHandler {

        @Override
        public Object handleResponse(HttpResponse response)
                throws ClientProtocolException, IOException {

            HttpEntity r_entity = response.getEntity();
            String responseString = EntityUtils.toString(r_entity);
            Log.d("UPLOAD", responseString);

            return null;
        }

    }

Answer 2

First of all your code could be optimized to the following:

$files = array('file1', 'file2', 'file3');
$path = 'elp/pendingimages/';

foreach ($files as $file) {
    if ($_FILES[$file]['error'] > 0) {
        echo 'Error: '. $_FILES[$file]['error'] .'<br />';
    }
    else {
        echo 'Upload: '. $_FILES[$file]['name'] .'<br />';
        echo 'Type: '. $_FILES[$file]['type'] .'<br />';
        echo 'Size: '. ($_FILES[$file]['size'] / 1024) .' Kb<br />';
        echo 'Stored in: '. $_FILES[$file]['tmp_name'] .'<br />';
    }

    $basename = basename($_FILES[$file]['name']);

    if (move_uploaded_file($_FILES[$file]['tmp_name'], $path . $basename) {
        echo "The file {$basename} has been uploaded";
    }
    else {
        echo 'There was an error uploading the file, please try again!';
    }
}

If you're using different field for each file then it's fine.

Next you can see what $_FILES array store in itself when it's multiple upload:

$_FILES = array(
    ['files'] => array(
        ['name'] => array(
            [0] => 'WALL_video.jpg'
            [1] => 'WALLc.jpg'
        )
        ['type'] => array(
            [0] => 'image/jpeg'
            [1] => 'image/jpeg'
        )
        ['tmp_name'] => array(
            [0] => '/tmp/phpnbKcdM'
            [1] => '/tmp/phpnrHSN1'
        )
        ['error'] => array(
            [0] => 0
            [1] => 0
        )
        ['size'] => array(
            [0] => 885968
            [1] => 839713
        )
    )
)

The following code will work for you if you're using one field with name like files[] as array of files.

$target_path = 'elp/pendingimages/';

foreach ($_FILES['files']['name'] as $index => $name) {
    if ($_FILES['files']['error'][$index] > 0) {
        echo 'Error: ' . $_FILES['files']['error'][$index] . '<br />';
    }
    else {
        echo 'Upload: '. $_FILES['files']['name'][$index] .'<br />';
        echo 'Type: '. $_FILES['files']['type'][$index] .'<br />';
        echo 'Size: '. ($_FILES['files']['size'][$index] / 1024) .' Kb<br />';
        echo 'Stored in: '. $_FILES['files']['tmp_name'][$index] .'<br />';
    }

    $path = $target_path . basename($name);

    if (move_uploaded_file($_FILES['files']['tmp_name'][$index], $path) {
        echo "The file {$name} has been uploaded";
    }
    else {
        echo 'There was an error uploading the file, please try again!';
    }
}
