There is ton of frameworks to provide a template language of an HTML page (smarty, twig, ...). The best and faster one we know is just called "PHP", and because Dolibarr already depends on PHP, using another framework may introduce a dependency on a third language to make templates. | There is ton of frameworks to provide a template language of an HTML page (smarty, twig, ...).

We must remind that template frameworks are just pre-processor, BEFORE PHP. They can't be faster than PHP alone. When we say "speed is increased because template framework use a cache", you must read in fact "the overtime spent by the framework is reduced by cache, not the speed of processing PHP file". We should say "any template framework has an overload over PHP, the cache of the template framework just reduces the slowing effect of using this framework", but not "the speed is increased, it is always decreased compared to pure PHP". | We must remind that template frameworks are just pre-processor, BEFORE PHP.

Above all, having a template system is completely possible by doing a "'''.tpl.php'''" file that dos not contains any logic code, but only HTML and print of variables. We get same result (but faster and easier to develop because it does not need to do all the setXXX before calling each template). All variables (known by code that include the template) are automatically known into a PHP template page. No risk to forget a set, and a lot of line of codes reduced, a lot of time and development errors are also saved. | Above all, having a template system is completely possible by doing a "'''.tpl.php'''" file that dos not contains any logic code, but only HTML and print of variables.
