PHP 8.4 introduces lazy objects, a powerful feature that delays object initialization until needed, enhancing performance and reducing memory usage. This article explores how to implement lazy objects using the new LazyObject class, provides tips for refactoring legacy code to leverage them, and highlights their benefits in optimizing resource-intensive applications like those relying on APIs or large datasets. Lazy objects offer developers an efficient way to simplify codebases while improving application speed and scalability.
