What are the potential conflicts that may arise when placing the search engine PHP file in a different directory?

Placing the search engine PHP file in a different directory may lead to conflicts with relative file paths or include statements. To solve this issue, you can use the `__DIR__` magic constant to dynamically reference the current directory of the file. 

<?php

// Use __DIR__ to get the current directory path
include_once __DIR__ . '/path/to/your/include/file.php';

// Use __DIR__ to construct file paths dynamically
$file = __DIR__ . '/path/to/your/file.txt';

// Use __DIR__ to include files from the current directory
include_once __DIR__ . '/search_engine.php';

?>
