What are some best practices for organizing and structuring PHP code when building a search function for a website?

When building a search function for a website in PHP, it's important to organize and structure your code in a way that promotes readability, maintainability, and efficiency. One best practice is to separate your search logic from your presentation logic by using a separate PHP file for handling the search functionality. This helps to keep your codebase clean and easy to understand. 

```php
// search.php

// Include necessary files and classes
require_once 'database.php';
require_once 'search_functions.php';

// Get search query from user input
$search_query = $_GET['query'];

// Perform search using a function from search_functions.php
$results = search($search_query);

// Display search results in the appropriate format
foreach ($results as $result) {
    echo '<div class="result">' . $result['title'] . '</div>';
}
```

In this code snippet, we have separated the search logic into a separate file called `search_functions.php` to keep the code organized. The `search.php` file handles the user input, performs the search using the `search()` function, and displays the results in the desired format. This approach makes it easier to maintain and update the search functionality in the future.
