How can PHP be used to dynamically generate and display images within a forum post or signature?

To dynamically generate and display images within a forum post or signature using PHP, you can write a script that retrieves the image URL from a database or external source, then use the PHP `echo` function to output the `<img>` tag with the image URL as the `src` attribute. 

&lt;?php
// Retrieve image URL from database or external source
$image_url = &quot;https://example.com/image.jpg&quot;;

// Output the image tag
echo &quot;&lt;img src=&#039;&quot; . $image_url . &quot;&#039; alt=&#039;Image&#039;&gt;&quot;;
?&gt;
