Does PHP need a separate templating language? After all, PHP itself functions as a templating engine? Why introduce another syntax, especially one that might limit front-end developers or force them into cumbersome workarounds? My experience, however, has taught me a crucial lesson: a dedicated template layer with well-defined boundaries is essential for building maintainable and secure web applications. It streamlines display logic, enforces separation of concerns, and protects against common vulnerabilities. In this article, we’ll dive into Twig 3, a widely-adopted templating engine without peer offering these benefits and more. It’s an excellent addition to any PHP project, new or old. by Oscar Merida
