php代码

$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";
}
?>
