We developed PHPTemplateLayer with the wide-ranging features and fast performance required for hundreds of our own websites. PHPTemplateLayer is possibly the easiest PHP template engine to install, setup and learn, even with no prior template experience. Since all control of template output remains with the PHP code, template tags are clean and easy, and no new security concerns are introduced. PHPTemplateLayer is 100% free to use and open source, and now even outputs minified HTML.
