What are the advantages and disadvantages of using Composer's PSR-4 autoloading compared to custom autoloading methods in PHP projects?

When working on PHP projects, one common issue is managing autoloading of classes efficiently. Composer's PSR-4 autoloading provides a standardized way to autoload classes based on namespaces, making it easy to manage dependencies. However, using custom autoloading methods can offer more flexibility and control over the loading process but may require more manual configuration and maintenance. 

// Using Composer's PSR-4 autoloading
require 'vendor/autoload.php';

// Using custom autoloading method
spl_autoload_register(function ($class) {
    $classPath = str_replace('\\', '/', $class) . '.php';
    include $classPath;
});
