如何使用变量在文件夹中移动图像

Question

我想插入原始图像和裁剪图像的值，我已经完成了裁剪图像。原始图像我已经传递了ajax中的src值，下一页我得到的值并插入该值，但不知道如何在一个文件夹中移动图像

   <div class="img-container">
      <img src="img/cropped-images/picture.jpg" alt="Picture">
    </div>
    <script>
        var original_image = $('img').prop('src');  
         $.ajax({
                        type:'POST',
                        url: "new_crop_image.php",
                        data: ({
                            'crop': result.toDataURL(),//this value i got and working fine
                            'image_var': original_image//this one not working,

                            }),
              }); 
     </script>

define('UPLOAD_DIR', 'img/cropped-images/');
$img = $_REQUEST['crop'];
$img = str_replace('data:image/png;base64,', '', $img);
$img = str_replace(' ', '+', $img);
$data = base64_decode($img);
$file = UPLOAD_DIR . uniqid() . '.png';
$success = file_put_contents($file, $data);
$result=$success ? $file : 'Unable to save the file.';
$explode=explode("/",$result);
$count=count($explode);
//echo $count.'<br>';
for( $i = 0; $i < $count; $i++ )
 {
if($i==2){
  $filename = $explode[2];  
 }
 }
