What are some best practices for handling data selection and manipulation in separate PHP pages?

When handling data selection and manipulation in separate PHP pages, it is best practice to keep your code organized and modular. One way to achieve this is by creating separate PHP files for selecting and manipulating data, and then including them in your main PHP file as needed. This helps improve code readability, maintainability, and reusability. 

// data_selection.php
<?php
// Perform data selection logic here
$data = // Retrieve data from database or other source
?>

// data_manipulation.php
<?php
// Perform data manipulation logic here
// Manipulate the $data variable as needed
?>

// main.php
<?php
include 'data_selection.php';
include 'data_manipulation.php';

// Use the $data variable for further processing
?>
