How can PHP scripts be used to predefine layouts for automatically generated HTML or PHP documents?

To predefine layouts for automatically generated HTML or PHP documents using PHP scripts, you can create template files with placeholders for dynamic content. Then, use PHP to include these template files and replace the placeholders with the actual content. This allows for consistency in the layout of your generated documents.

<?php
// Define your template file with placeholders
$template = file_get_contents('template.php');

// Replace placeholders with actual content
$content = 'This is the dynamic content.';
$template = str_replace('{{content}}', $content, $template);

// Output the final document
echo $template;
?>
