How can one improve the efficiency of the image resizing function provided in the code snippet?

The efficiency of the image resizing function can be improved by using a more optimized algorithm or library for image manipulation. One way to achieve this is by utilizing the GD or Imagick extension in PHP, which provides better performance for image processing tasks. By leveraging these extensions, the resizing function can be optimized to handle large images more efficiently. 

```php
function resize_image($source_image_path, $dest_image_path, $max_width, $max_height) {
    $image = new Imagick($source_image_path);
    $image->resizeImage($max_width, $max_height, Imagick::FILTER_LANCZOS, 1, true);
    $image->writeImage($dest_image_path);
}
```

In this code snippet, we have utilized the Imagick extension in PHP to resize the image using the `resizeImage` method with the Lanczos filter for better quality. This approach can significantly improve the efficiency of the image resizing function compared to the previous implementation.
