CHANGE PHP STATUS [closed]

I am having a problem when changing the status of the users of my database, when I am going to change the status of some user it does not approve the user of that line but last user what can be?

logado.php

  <?php  
                //Consulta
                $buscarusuario=$pdo->prepare("SELECT * FROM usuario");
                $buscarusuario->execute();

                //atribuindo dados á variavel
                $linha = $buscarusuario->fetchAll(PDO::FETCH_ASSOC);

                //percorrendo a variavel para listar os dados
                foreach ($linha as $listar) {
                    $iduser = $listar['id'];
                    echo "<tr>";
                    echo " <td>".$listar['id']."</td>";
                    echo "<td>".$listar['nome']."</td>";
                    if($listar['status'] > 0 ){
                    echo "<td class='success text-success'>Aprovado 
  <form method='post' action='pg/mudastatus.php'>
    <input type='hidden' name='desaprovauser' value='$iduser'>
      <button type='submit' class='btn btn-xs btn-success alinha-btn' name='desaprova' value='desaprovar'>Desaprovar</button>

                    </td>";
                  }else{
                    echo "<td class='danger text-danger'> Aguardando aprovação 
  <form method='post' action='pg/mudastatus.php'>
   <input type='hidden' name='aprovauser' value='$iduser'>
   <button type='submit' class='btn btn-xs btn-danger alinha-btn' name='aprova' value='aprovar' >Aprovar</button>
</form>

                    </td>";
                  } 
  }
              ?>

mudastatus.php

    if(isset($_POST['aprova'])){

   $atualizarstatus = $pdo->prepare("UPDATE usuario SET status=1 WHERE id='".$_POST["aprovauser"]."' ");
   $atualizarstatus->execute();
   $linha = $atualizarstatus->rowCount();

   if($linha > 0){
     header("location:../logado.php");
   }else{
    echo "Erro ao Mudar status";
   }
}elseif (isset($_POST['desaprova'])){

   $atualizarstatus = $pdo->prepare("UPDATE usuario SET status=0 WHERE id='".$_POST["desaprovauser"]."' ");
   $atualizarstatus->execute();
   $linha = $atualizarstatus->rowCount();

   if($linha > 0){
