Working with PHP and Mysql code in TWIG - php

Question

I am working with the TWIG framework for php, and would like to know how i would be able to include these php files inside my php code like i normally do.
<?php
session_start();
include("includes/db.php");
include("functions/searchfunctions.php");
include("functions/userSearchSession.php");
?>
The db file establishes the connection through mysqli to the database.

In your comments you mentioned you are using the Slim framework, which has an extension to support Twig templates.
Using the extension however, requires some additional setup though, you must install the extention, called Slim Views, and also the Twig core from within composer. Slim Views does not list Twig as a dependancy.
To get this working:
Use composer to get add both Slim Views And Twig
$ php composer require slim/views
$ php composer require twig/twig:~1.0
Configure your Slim Framework $app to use the new tempting engine.
$view = $app->view();
$view->parserOptions = array(
'debug' => true,
'cache' => dirname(__FILE__) . '/cache'
);
$view->parserExtensions = array(
new \Slim\Views\TwigExtension(),
);
At this point, Slim Framework is now using Twig when rendering pages. You can now do all of your includes and pass the variables to Twig:
<?php
// ./Slim_app.php
require 'vendor/autoload.php';
/*
* foo.php contains the following:
* <?php
* $foo = bar;
*
*/
require 'foo.php';
$app = new \Slim\Slim(array(
'view' => new \Slim\Views\Twig()
));
$view = $app->view();
$view->parserOptions = array(
'debug' => true,
'cache' => dirname(__FILE__) . '/cache'
);
$view->parserExtensions = array(
new \Slim\Views\TwigExtension(),
);
$app->get('/hello', function () use ($app, $foo) {
//twig_template.html.twig exists in the templates directory.
//(./templates/twig_template.html.twig)
$app->render('twig_template.html.twig', array('foo' => $foo));
});
$app->run();
?>
{# ./templates/twig_template.html.twig #}
{{ foo }}
Navigating to Slim_app.php/hello now displays the following:
