    He’s using myslqli, it won’t change, I think the problem is here, email='"($_POST['email'])." ' , ta concatenated wrong, leaves it like this: email='". $_POST['email']."'

It is problem in concatenation (missing the point "."):

$sql= mysqli_query ($conexao,"select * from usuario where email='."($_POST['email'])."' and senha='".($_POST['senha_usu'])."' limit 1") or die("Erro");
