How to display the number of incoming applications?

Question

JavaScript

Hello!
There is a menu and it is written entirely in PHP:

<?php
     session_start();
     if($_GET['act']==="myfriends") $pp="active";
     if($_GET['act']==="outbox") $vp="active";
     if($_GET['act']==="inbox") $tp="active";
     if($_GET['act']==="subscribers") $cht="active";
     if($_GET['act']==="poisk") $pt="active";
     if(isset($_SESSION['login'])){
         $satira= '
               <div id="all_friendss_users_class">
             <div id="kostr_doipit">
       <button class="menu-toggle" onclick="loaerj();">Меню</button>
               <nav id="menu">
     <ul id="super-list">
         <li class="main-menu__item main-menu__item--0 '.$pp.'" ><a href="?act=myfriends">Мои друзья</a></li>
         <li class="main-menu__item main-menu__item--1 '.$vp.'" ><a href="?act=outbox">Исходящие</a></li>
         <li class="main-menu__item main-menu__item--2 '.$tp.'" ><a href="?act=inbox">Входящие '.$_SESSION['count'].'</a></li>
         <li class="main-menu__item main-menu__item--3 '.$cht.'" ><a href="?act=subscribers">Подписчики</a></li>
         <li class="main-menu__item main-menu__item--4 '.$pt.'" ><a href="?act=findnew">Найти друзей</a></li>
     </ul>
</nav>
             </div>
         </div>
         ';
     }
     ?>

Maybe it looks ugly, so I'm waiting for suggestions for improvement :)
There is a code that should return a value for $_SESSION['count']

$poisk= $_GET['act'];
if($poisk === "inbox"){
       if(!isset($_SESSION['login'])){
           $text="Несанкционированный доступ в систему";
       }
         $sql = "SELECT name,familiya,img,link,id FROM users WHERE id IN (SELECT id_users_from FROM friends WHERE id_users_to=? AND status_to_keepass='IN PROCESS')";
       $sth= $DataBaze->prepare($sql);
       $sth->execute([$_SESSION['id_user']]);
       if($sth->rowCount()>0){
           $_SESSION['count']= $sth->rowCount();
           $obrabotka= $sth->fetchAll();
    
     }
   }

Is it possible to solve by JS or Node.js or JQUERY method

Answer 1

Make an Ajax request to the method that will return data to you, and then write down this data where necessary
