How to pass a php variable to a twig template

Question

I am using twig for the first time and I want to pass a variable to the template, So How I can pass a new template variable? I want to add something like :

{{ Total_project }}

This variable is a return for a function that count the projects and return the total:

public function total_projects(){
        if ($result = mysqli_query($conn, "SELECT project_id as total_project FROM Projects")) {
            $row_cnt = mysqli_num_rows($result);
            }
    }

What shall I do exactly?

You pass the variables when you render the template. See [the docs](https://twig.symfony.com/doc/2.x/api.html#rendering-templates) for more info. — rickdenhaan, Feb 17 '18 at 00:21
Call the function _before_ render, and pass the result into twig per the docs @rickdenhaan pointed you at. Also, your function doesn't return anything... — Jonnix, Feb 17 '18 at 01:07

Rendering with template :

    public function total_projects(){
    if ($result = mysqli_query($conn, "SELECT project_id as total_project FROM Projects")) {
        $row_cnt = mysqli_num_rows($result);
        $total_project = $result['total_project'];
    }

    return $this->render('index.html.twig', array(
        'Total_project' => $total_project
    ));
}
