This is Jason's Responsive Background Image Twig Macro translated into PHP for use with ACF image fields:

<?php function responsive_ACF_background_image($image, $display_style, $css_path) {
  $retina_style = $display_style . "2x";
  echo "<style>
      $css_path {
          background-image: url(\"" . $image[sizes][$display_style] . "\");
      }
 @media

/**
* WordPress function to create HTML5 image element with 'srcset' and 'sizes' attributes for JPEGs and PNGs. 
* Paste in to functions.php for use elsewhere in theme. Images in 'srcset' are created from all WordPress registered image sizes.
* Mime types 'image/jpg', 'image/png', and 'image/gif' are returned appropriately.
