What are the best practices for handling file paths in PHP projects when using an IDE like PhpStorm for development?

When working on PHP projects in an IDE like PhpStorm, it's important to handle file paths correctly to avoid issues with file inclusion or manipulation. One best practice is to use the `__DIR__` magic constant to reference the current directory and build file paths relative to it. This ensures that the paths are always correct regardless of the file's location in the project directory structure.

// Example of handling file paths using __DIR__ in PHP
$filePath = __DIR__ . '/includes/config.php';
include $filePath;
