Android uploads images to PHP server

Android Code

PHP code

$data = file_get_contents (' php://input ');
$time = Date ("Ymdhis");
$rand = rand (0,100);
$filename = $_server[' Document_root '). ' /image/'. $time. $rand. JPG ';
while (File_exists ($filename))
{
$filename = $_server[' Document_root '). ' /image/'. $time. Rand (0,100). JPG ';
}

echo $filename;
$handle = fopen ($filename, ' w ');
if ($handle)
{

Fwrite ($handle, $data);
Fclose ($handle);

echo "Success";
}
?>

The above describes the Android upload image to the PHP server, including the aspects of the content, I hope the PHP tutorial interested in a friend helpful.
