How can the design and layout of PHP scripts be improved for better readability and user experience in a forum environment?

To improve the design and layout of PHP scripts in a forum environment for better readability and user experience, it is important to separate the logic from the presentation. This can be achieved by using a templating system like Smarty or creating separate files for HTML markup. Additionally, organizing the code into functions and classes can make it more modular and easier to maintain.

<?php

// Example of separating logic from presentation using a templating system like Smarty

require_once('smarty/Smarty.class.php');

$smarty = new Smarty;

// Assign variables
$smarty->assign('title', 'Forum Title');
$smarty->assign('posts', $posts);

// Display template
$smarty->display('forum_template.tpl');

?>
