I have a vector that receives data coming from a socket that I use for notifications to the user, however every time I change pages I lose all the value coming from this variable, I'm using angular on the front end. How can I navigate the system normally without losing the values inside my vector? PS: If anyone knows of any logic, tutorial related to angular and notifications (facebbok style, twitter, etc), can you pass me that I will study. Thanks

You can create a service and store it, because when the page is updated the service is not restarted.
angular.module('app', [''])
.service('myService', myService);
function myService($http) {
var dados;
function setDados(valor) {
dados = valor;
}
function getDados() {
return dados
}
}
After that, just inject the service on your controller and access the functions
angular.module('heroApp', [])
.controller('myCtrl', myCtrl)
function myCtrl($scope, myService) {
var contato = {
email:'[email protected]',
nome:'Fulano'
}
myService.setDados(contato);
console.log(myService.getDados())
}

This example illustrates the basic creation of a session anchored to a global variable. But the overuse of global variables brings serious application risks. The comments above a colleague indicates a $_SESSION study material I suggest you study this before implementing. Also this Link . I hope I have helped you study well.
<?php
session_start();
$st=mysqli_query($conn,"select * from usuarios where login='$doc'");
$result=mysqli_fetch_array($st);
$_SESSION['usuario'] = $result['nome'];
?>
<html>
<head>
</head>
<body>
<?php
if ($_SESSION['usuario'] === false){
Session_destroy();
header("location: index"); exit;
}
<li class="dropdown">
<a href="" class="dropdown-toggle" data-toggle="dropdown"><?php echo $_SESSION['usuario'] ?> <span class="caret"></span></a>
<ul class="dropdown-menu">
<li><a href="editarperfil">Editar</a></li>
<li><a href="logout">Sair</a></li>
</ul>
</li>
</ul>
?>
</body>
