What are the best practices for handling class names in PHP to ensure compatibility across different servers?

When dealing with class names in PHP, it is important to follow the PSR-4 standard for autoloading classes to ensure compatibility across different servers. This standard dictates that class names should be in StudlyCaps format and match the directory structure of the file. By adhering to this standard, you can avoid any naming conflicts and easily autoload classes on various servers. 

// Autoloading classes using PSR-4 standard
spl_autoload_register(function ($class) {
    // Convert class name to file path
    $file = __DIR__ . '/' . str_replace('\\', '/', $class) . '.php';
    
    // Check if file exists and include it
    if (file_exists($file)) {
        include $file;
    }
});
