在上传复制图像并移动到其他文件夹

I am currently using the following to upload an image into a folder but I am finding that for my specific purpose I need to copy the image as it is uploaded and add it to a folder a little higher up in the directory.

Example: The image file gets uploaded to /folder/folder/images and this is good. I need it there. However, I also need a copy with the same file with the same filename here: /folder/images

Here is the PHP I am using to upload the image to begin with. How can I mdify it to also copy and add to the other folder as a new image is uploaded?

<?php
  // A list of permitted file extensions
  $allowed = array('png', 'jpg', 'gif','zip');

  if(isset($_FILES['file']) && $_FILES['file']['error'] == 0){

  $extension = pathinfo($_FILES['file']['name'], PATHINFO_EXTENSION);

  if(!in_array(strtolower($extension), $allowed)){
  echo '{"status":"error"}';
  exit;
}

  if(move_uploaded_file($_FILES['file']['tmp_name'],
  'images/'.$_FILES['file']['name'])){
  $tmp='images/'.$_FILES['file']['name'];
  echo 'images/'.$_FILES['file']['name'];
  //echo '{"status":"success"}';
  exit;
  }
}

echo '{"status":"error"}';
exit;
?>

UPDATE:

Here is the code that got things working for me:

<?php
  // A list of permitted file extensions
  $allowed = array('png', 'jpg', 'gif','zip');

  if(isset($_FILES['file']) && $_FILES['file']['error'] == 0){

  $extension = pathinfo($_FILES['file']['name'], PATHINFO_EXTENSION);

  if(!in_array(strtolower($extension), $allowed)){
  echo '{"status":"error"}';
  exit;
 }

  if(move_uploaded_file($_FILES['file']['tmp_name'],'images/'.$_FILES['file']['name'])){
   $tmp='images/'.$_FILES['file']['name'];
   $new = '../images/'.$_FILES['file']['name']; //adapt path to your needs;
   if(copy($tmp,$new)){
     echo 'images/'.$_FILES['file']['name'];
   //echo '{"status":"success"}';
  }
  exit;
 }
}

echo '{"status":"error"}';
exit;
?>

Based on the comments on your question:

if(move_uploaded_file($_FILES['file']['tmp_name'],'images/'.$_FILES['file']['name'])){
    $tmp='images/'.$_FILES['file']['name'];
    $new = 'newFolder/'.$_FILES['file']['name']; //adapt path to your needs;
    if(copy($tmp,$new)){
        echo 'images/'.$_FILES['file']['name'];
        //echo '{"status":"success"}';
    }
    exit;
}

Just copy it!

$source='folder/folder/images/imageexists.jpg';
$destination='folder/images/imagedoesnotexists.jpg';
if(!copy($source, $destination)){
    //copy failed
}

Is good idea to use copy() function.

if(move_uploaded_file($_FILES['file']['tmp_name'],
  'images/'.$_FILES['file']['name'])){
  $tmp='images/'.$_FILES['file']['name'];
  echo 'images/'.$_FILES['file']['name'];

  copy($tmp,'/folder/images/'.$_FILES['file']['name']);
  //echo '{"status":"success"}';
  exit;
  }
