What are the potential pitfalls of integrating Composer and its autoload function into a PHP project?

One potential pitfall of integrating Composer and its autoload function into a PHP project is that if the autoloader is not properly configured or if there are conflicts with other autoloaders, it can lead to class loading issues and cause the application to break. To avoid this, ensure that Composer's autoload function is set up correctly and that any conflicts with other autoloaders are resolved.

// Include Composer's autoloader
require 'vendor/autoload.php';
