What is the recommended way to include a background image in PHP using CSS?

When including a background image in PHP using CSS, the recommended way is to echo out the CSS code within the HTML document. This can be done by embedding the CSS code within a <style> tag or linking to an external CSS file that contains the background image styling. By dynamically generating the CSS code in PHP, you can easily change the background image based on certain conditions or variables.

&lt;?php
$background_image = &quot;path/to/background.jpg&quot;;
echo &#039;&lt;style&gt;
        body {
            background-image: url(&#039; . $background_image . &#039;);
            background-size: cover;
            background-position: center;
        }
      &lt;/style&gt;&#039;;
