Answer
Autoloading automatically loads classes when first referenced, commonly via spl_autoload_register or Composer.
Quick Answer
Autoloading automatically loads class files when a class is first used. No manual require needed. PHP has spl_autoload_register() for custom autoloaders. Composer generates an optimized PSR-4 autoloader that maps namespace prefixes to directory paths. Just include vendor/autoload.php once and all classes load automatically. Essential for any modern PHP project.
