Is it common for PHP website scripts to lack visible HTML content for inserting ads?

It is not common for PHP website scripts to lack visible HTML content for inserting ads as ads are typically inserted within the HTML code. To solve this issue, you can modify the PHP script to include HTML code where you want the ads to appear. This can be done by echoing out the HTML content within the PHP script.

<?php
// Your PHP code here

// Inserting ad HTML content
echo '<div class="ad">Ad content goes here</div>';
?>
