Could someone put a simple code on how to use the global variable $ _SESSION?
The problem is that when logging in, I do not know how to save the user in the global variable $ _SESSION and how to use it later in the other pages.

try {
$base = new PDO("pgsql: host=localhost; port=5432; dbname=sistema", "postgres", "123456");
$base->SetAttribute(PDO::ATTR_ERRMODE, PDO:: ERRMODE_EXCEPTION);
$pg = "select * from usuarios where usuario = :usuario or correo_usuario = :usuario";
$resultado = $base->prepare($pg);
$usuario = htmlentities(addslashes($_POST['usuario']));
$clave = htmlentities(addslashes($_POST['clave']));
$resultado->Execute(array(":usuario" => $usuario));
$registro = $resultado->fetch(PDO::FETCH_ASSOC);
if(password_verify($clave, $registro['clave'])){
session_start();
$_SESSION['login']=$registro;
header("location:cronograma.php");
}else{
session_start();
$_SESSION['error']=$alerta;
header("location:acceso.php");
}
} catch (Exception $e) {
die("Error: " . $e->GetMessage());
}
With this code you can start your session_start , the user is saving in $_SESSION['login'] , to recover the data you need from your logged in user you would have to add another parameter that you already have declared in your database, for example , $_SESSION['login']['id_usuario'] , so you retrieve the id of the user entered. If in your database you have nombre then for the name you would put $_SESSION['login']['nombre'] the value you want to recover you declare it in the second dimension of the array.
