Show result of query with count - php

Question

I'm making a query with a count statement and I wanna show the result
something like this
I have a file with name functions.php where I make the query in a (obviously) function.
those are my functions:
function conection($bd_config){
try {
$conection = new PDO('mysql:host=localhost;dbname='.$bd_config['database'], $bd_config['user'], $bd_config['pass']);
return $conection;
} catch (PDOException $e) {
return false;
}
}
function checksession(){
if (!isset($_SESSION['user'])) {
header('Location: ' . ROUTE. '/login.php');
}
}
#$us = $_SESSION['USER'][0];
function notification_count($conexion, $us){
$count = $conection->prepare('SELECT * FROM postulate WHERE du = $us AND seen = 0');
$count->execute();
$total = $count->rowCount();
$total = $count->fetchColumn();
return $total;
}
I have another file with name lateral.php where I "call" the function and the view of latera.view.php
lateral.php:
<?php session_start();
require 'extras/config.php';
include 'functions.php';
checksession();
$conection = conection($bd_config);
$quantity = notification_count($conection, $us);
require "views/lateral.php";
lateral.view.php:
<div class="block-section text-center ">
<img src="images/<?php echo($_SESSION['user'][14]) ?>" class="img-rounded" alt="">
<div class="white-space-20"></div>
<h4><?php echo($_SESSION['user'][3]) ?></h4>
<div class="white-space-20"></div>
<ul class="list-unstyled">
<li> Messages </li>
<li> Notifications<?php here is where I want the total of the query ?></li>
<li> Change password</li>
</ul>
<div class="white-space-20"></div>
</div>
</div>
<div class="col-md-9 col-sm-9">

Answer 1

in the file of functions I need to make my query like this:
function notifications_count($conection, $us){
$count= $conection->prepare("SELECT COUNT(*) FROM postul WHERE du = $us AND seen = 0");
$count->execute();
$number_notu = $count->fetchAll();
return $number_notu;
}
then in the file of notifications.php where onlye I print code and make a require of the view(HTML) I need to put something like this:
<?php session_start();
require 'extra/config.php';
require 'functions.php';
$conection = conection($bd_config);
if (!$conection) {
header('Location: error.php');
}
$postul= get_people($notu_config['post_notu'], $conection, $us);
if (!$postul) {
$vacio = "<li>The aren't any notifications</li>";
}
$total_notu = notu_count($conection, $us);
require "views/notifications.php";
and in the view of notifications where I print only HTML I need to make a foreach:
<div class="block-section text-center ">
<img src="images/<?php echo($_SESSION['user'][14]) ?>" class="img-rounded" alt="">
<div class="white-space-20"></div>
<h4><?php echo($_SESSION['user'][3]) ?></h4>
<div class="white-space-20"></div>
<ul class="list-unstyled">
<li> Messages</li>
<?php foreach ($total_notu as $notu) : ?>
<li> Notificaciones <span class="badge "><?php echo "$notu[0]"; ?></span></li>
<?php endforeach; ?>
<li> Change password</li>
</ul>
<div class="white-space-20"></div>
</div>
</div>
<div class="col-md-9 col-sm-9">
