你可以试着这样做，

 <?php

if (isset($_POST['upload_Btn'])) {
    $ext = end((explode(".", $_FILES['gambar']['name'])));
    $file_name = microtime() .".".$ext;
    $target = "uploaddosen/". microtime() .".".$ext;


    if (move_uploaded_file($_FILES['gambar']['tmp_name'],$target)) {
        $msg = "Image uploaded successfully";
        // Write your db insert code here
        echo json_encode(array('msg' => $msg, 'image' => $file_name));
       exit();

    }else{
        $msg = "Failed to upload image";
    }

  echo $msg;

}
