What are the benefits of using PHP's spl_autoload_register function for class loading in a CMS?

When developing a CMS in PHP, managing class loading efficiently is crucial for maintaining a clean and organized codebase. PHP's spl_autoload_register function allows us to register multiple autoload functions, which will be called in a specific order when a class is not found. This helps in dynamically loading classes on-demand, reducing the need for manual require or include statements throughout the code. 

// Registering autoload function using spl_autoload_register
spl_autoload_register(function ($class) {
    // Convert class namespace to file path
    $file = str_replace('\\', '/', $class) . '.php';
    
    // Check if the file exists, then include it
    if (file_exists($file)) {
        include $file;
    }
});
