Value does not fit inside the text box

Question

Hey, what’s up, guys? So, I have a problem, I made a function that returns data from a certain table field, so to insert it into the text box of a form; but, the returned value of the field appears on top of the text box, not inside the value="" attribute. I’m only using HTML and PHP to build the algorithm and, I intend not to use javascript for now. If someone answers, I thank you very much for your help, because I am not able to solve such a problem.

      //////////////// Editar ///////////////////////
  function select($id)
  {
    global $conn;
    $stmt = $conn->prepare("SELECT usuario FROM usuarios WHERE id = $id");
    $stmt->execute();
    $row_user = $stmt->fetch(PDO::FETCH_ASSOC);
    echo $row_user['usuario'];
  }
  ///////////////////////////////////////////////
  if (isset($_GET['id']) and $_GET['acao'] == 'editar' and $_GET['campo'] == 'usuario')
  {
    echo ('
      <form method=post>
        <input type=text name=edit_usr value='.select($_GET['id']).'><br>
        <input type=submit name=edit_envia value=Editar>
      </form>

    ');

You’re giving a echo in the function when it should return the value with a return.

Exchange the echo $row_user['usuario']; for return $row_user['usuario'];.
