In what scenarios is it advisable to use relative file paths instead of absolute URLs with the "include" function in PHP?

Using relative file paths instead of absolute URLs with the "include" function in PHP is advisable when you want to make your code more portable and avoid hard-coding specific server paths. Relative file paths are easier to manage and maintain, especially when moving your code to different environments or servers. By using relative paths, you can ensure that your code remains functional regardless of the server configuration.

<?php
// Using relative file paths with the include function
include 'path/to/file.php';
?>
