What are the potential pitfalls of using multiple includes in PHP files?

Using multiple includes in PHP files can lead to issues such as conflicts between included files, redundant code execution, and decreased readability. To avoid these pitfalls, it is recommended to use include_once or require_once functions instead of include or require to ensure that a file is only included once. This helps prevent duplicate declarations and conflicting functions or classes. 

<?php
require_once 'file1.php';
require_once 'file2.php';
require_once 'file3.php';
// Rest of the code
?>
