    Go to PATH_TO_XAMPP\apache\conf\extra\httpd-vhosts.conf. Open this file and uncomment line 19. You can add your virtual host on line 36.

    <VirtualHost *:80>
        DocumentRoot C:\YOUR_NEW_PATH
        ServerName NEW_SERVER_NAME.localhost
        <Directory C:\YOUR_NEW_PATH>
            Order allow,deny
            Allow from all
        </Directory>
    </VirtualHost>

    Open your drivers hosts file at C:\Windows\System32\drivers\etc\hosts.

    Add

    127.0.0.1 NEW_SERVER_NAME.localhost #NEW_SERVER_NAME

    to the end of the file (before the Spybot - Search & Destroy stuff if you have that installed).

Save this file and Restart Apache and enjoy.

By using HTML5 approach, multiple files can be uploaded through a single click. Please look at the script below.


<input type="file" name="multifile[]" multiple="multiple">


 multiple="multiple"  is an HTML5 construct, to select multiple files at once. Now come to PHP.


$files=array();

$fdata=$_FILES['multifile'];

if(is_array($fdata['name'])){

for($i=0;$i<count($fdata['name']);++$i){

$files[]=array(

'name' => $fdata['name'][$i],

'tmp_name' => $fdata['tmp_name'][$i],

);   }      }

else $files[]=$fdata;

foreach ($files as $file) {

$target_path = $target_path . basename($file['name']);

move_uploaded_file($file['tmp_name'], $target_path)

}
