In PHP, what are some considerations when dealing with a large number of classes/interfaces in an autoloader scenario?

When dealing with a large number of classes/interfaces in an autoloader scenario in PHP, it's important to optimize the autoloading process to prevent performance issues. One way to do this is by using a more efficient autoloading mechanism like Composer's classmap feature, which generates a map of all classes/interfaces in the project. This reduces the number of file system checks needed during autoloading, improving performance.

// Composer autoloader with classmap optimization
require 'vendor/autoload.php';
