How to get the file name and file size for the attachment of my custom post type

I am making a plugin with a custom post_type called circular I use a meta box to upload PDF or image file now I can retrive the url of the file but how can I get the file name and size from my custom post_type meta field .

Here is my Meta Box code 

function add_custom_meta_boxes() {

    // Define the custom attachment for posts
    add_meta_box(
        'wp_custom_attachment',
        'Custom Attachment',
        'wp_custom_attachment',
        'circular',
        'side'
    );

} // end add_custom_meta_boxes
add_action('add_meta_boxes', 'add_custom_meta_boxes');

function wp_custom_attachment() {

    wp_nonce_field(plugin_basename(__FILE__), 'wp_custom_attachment_nonce');

    $html = '<p class="description">';
        $html .= 'Upload your PDF here.';
    $html .= '</p>';
    $html .= '<input type="file" id="wp_custom_attachment" name="wp_custom_attachment" value="" size="25" />';

    echo $html;

} // end wp_custom_attachment


function save_custom_meta_data($id) {

    /* --- security verification --- */
    if(!wp_verify_nonce($_POST['wp_custom_attachment_nonce'], plugin_basename(__FILE__))) {
      return $id;
    } // end if

    if(defined('DOING_AUTOSAVE') && DOING_AUTOSAVE) {
      return $id;
    } // end if

    if('circular' == $_POST['post_type']) {
      if(!current_user_can('edit_page', $id)) {
        return $id;
      } // end if
    } else {
        if(!current_user_can('edit_page', $id)) {
            return $id;
        } // end if
    } // end if
    /* - end security verification - */

    // Make sure the file array isn't empty
    if(!empty($_FILES['wp_custom_attachment']['name'])) {

        // Setup the array of supported file types. In this case, it's just PDF.
        $supported_types = array('application/pdf');

        // Get the file type of the upload
        $arr_file_type = wp_check_filetype(basename($_FILES['wp_custom_attachment']['name']));
        $uploaded_type = $arr_file_type['type'];

        // Check if the type is supported. If not, throw an error.
        if(in_array($uploaded_type, $supported_types)) {

            // Use the WordPress API to upload the file
            $upload = wp_upload_bits($_FILES['wp_custom_attachment']['name'], null, file_get_contents($_FILES['wp_custom_attachment']['tmp_name']));

            if(isset($upload['error']) && $upload['error'] != 0) {
                wp_die('There was an error uploading your file. The error is: ' . $upload['error']);
            } else {
                add_post_meta($id, 'wp_custom_attachment', $upload);
                update_post_meta($id, 'wp_custom_attachment', $upload);     
            } // end if/else

        } else {
            wp_die("The file type that you've uploaded is not a PDF.");
        } // end if/else

    } // end if

} // end save_custom_meta_data
add_action('save_post', 'save_custom_meta_data');

function update_edit_form() {
    echo ' enctype="multipart/form-data"';
} // end update_edit_form
add_action('post_edit_form_tag', 'update_edit_form');

do out put the link of that file 

<?php $img = get_post_meta(get_the_ID(), 'wp_custom_attachment', true); ?>
<a href="<?php echo $img['url']; ?>"> Download PDF Here</a>

First need to get the file url the we can get the size and name . here wp_custom_attachment is the custom field id.

 // retrieve file of the custom field 
 $file = get_post_meta(get_the_ID(), 'wp_custom_attachment', true); 

 //get the url
 $url = $file['url'];

 //Replace url to directory path
  $path = str_replace( site_url('/'), ABSPATH, esc_url( $url) );

  if ( is_file( $path ) ){
    $filesize = size_format( filesize( $path ) );
    $filename = basename($path); 
  }

            echo '<p>Name: ' . $filename . '</p>';
            echo '<p>Size: ' . $filesize . '</p>';

If you can get the attachment ID number ($attachment_id below) you should be able to do something like this to get the name/size:

$attachment_id = 'YOUR_PDF_ID';
$attahment_file = get_attached_file( $attachment_id );

function getSize($file) {
    $bytes = filesize($file);
    $s = array('b', 'Kb', 'Mb', 'Gb');
    $e = floor(log($bytes)/log(1024));
    return sprintf( '%.2f ' . $s[$e], ( $bytes/pow( 1024, floor($e) ) ) );
}

echo '<p>Name: ' . basename( $attahment_file ) . '</p>';
echo '<p>Size: ' . getSize( $attahment_file ) . '</p>';

I found the "getSize" function on another post here. It was more accurate than using the native PHP "filesize" function in terms of matching the size shown in the WP media library meta.
