Retain the original name of the image on resize

Question

I need to resize a few existing images in my upload directory so doing some tests with wp_get_image_editor. Please check the example code below.

$img = wp_get_image_editor( ABSPATH.'test/flower.jpg' );
if ( ! is_wp_error( $img )) {
    $img->resize( 800, NULL, false ); //resize to max-width of 800px.
    $filename = $img->generate_filename( 'custom-suffix-string', NULL, 'jpg');
    $saved = $img->save($filename);

    //information returned by $saved
    echo "Filename: ".$saved['file']."<br>";
    }

As you can see I can add a custom suffix with line-4 of the code. So the name of my resized file will be flower-custom-suffix-string.jpg. The problem is I need it to return as NULL.

If I use generate_filename( NULL, NULL, 'jpg'); the echoed result is Filename: flower-800x667.jpg. So basically I am trying to get the name of the RESIZED image as flower.jpg same as original and get rid of -800x667 from the name. If the process overwrites/deletes the original file, that would not be a problem. Any suggestions or any other way to achieve this ? TIA.

UPDATE : I ended up using the code below. Thanks for the tip @Zakir

$filename = $img->generate_filename( 'temp', NULL, NULL);
$new_name = str_replace('-temp', '', $filename);
$resized_img = $img->save($new_name);

You can simply use preg_replace() functions to remove -800x667 (or any height) from the image. Like this-

$image = generate_filename( NULL, NULL, 'jpg');
echo preg_replace( '/-800x[0-9]{2,4}/', '', $image );
