Why using TWIG?? And what about : include and require ??? its more easy with... no??

For me its more logic to do this :

<?
require_once('public/php/header.inc.php');

$id = strtolower(strip_tags(trim($_GET['id'])));
switch ($id){
    case 'frais':
        $title = "some title";
        $data = "some data to change"
        include_once ('about.php')';
        break;
et etc...... 

require_once('public/php/footer.inc.php');?>

and in links just writing this code ===> 

<a href="index.php?id=frais</a>

So i would like to know what do you think about it? is my version of code is old and nobody do this anymore? For me i have a lot of difficults to understand Twig and Slim...

So the "require/include" functions of old, are that, old. We, PHP, have moved towards autoloading code via an autoloader. Look at PSR-4 for an example to what the PSR autoloading standards are. The PHP world is currently at this level. Using require should really only be used once, and that is to require your autoloader. Like you did with Slim, or if you have a bootstrap.php file.

As for twig, its currently the most used and standard for templating. PHP doesnt handle templating well natively, so the Symfony people wrote Twig. Since then, Smarty, Blade, and Plates have all come alive as an alternative to Twig. But Twig is one of the best tools Ive used as a developer.

Also, looking at the "a href" line you added below the code, thats horrible practice, and is very open to SQL injection, which would allow your database to be attacked.

Maximleguennec I'm kind of with you, as in I don't understand the importance of Twig. I get composer and Slim, but Twig just seems like added wait. I don't know. Maybe I'm missing something.
