What are the best practices for organizing and naming included files in PHP projects to avoid errors?

Organizing and naming included files in PHP projects is crucial to avoid errors such as file not found or naming conflicts. To ensure smooth inclusion of files, it is recommended to use a clear and consistent naming convention, create a separate directory for included files, and include files using absolute paths rather than relative paths.

// Example of including files using absolute paths and organizing them in a separate directory

// Define the base directory for included files
define('INCLUDE_PATH', __DIR__ . '/includes/');

// Include a file using absolute path
include(INCLUDE_PATH . 'config.php');
include(INCLUDE_PATH . 'functions.php');
