If you want to open the modal on the current page, you can do something like this:

 <a href="#" class="btn btn-primary" data-toggle="modal" data-target="#modal-<?php echo $row['id_user']; ?>">Open modal</a>

and the modal should look like this:

<div class="modal-content" id="modal-<?php echo $row['id_user']; ?>">
  <div class="modal-header">
    <button type="button" class="close" data-dismiss="modal">&times;</button>
    <h4 class="modal-title">Modal Header</h4>
  </div>
  <div class="modal-body">
    <p>Some text in the modal.</p>
  </div>
  <div class="modal-footer">
    <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
  </div>
</div>

With the official bootstrap modal example:

<!-- Button trigger modal -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal-<?php echo $row['id_user']; ?>">
  Launch demo modal
</button>

<!-- Modal -->
<div class="modal fade" id="exampleModal-<?php echo $row['id_user']; ?>" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel-<?php echo $row['id_user']; ?>" aria-hidden="true">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="exampleModalLabel-<?php echo $row['id_user']; ?>">Modal title</h5>
        <button type="button" class="close" data-dismiss="modal" aria-label="Close">
          <span aria-hidden="true">&times;</span>
        </button>
      </div>
      <div class="modal-body">
        ...
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>
</div>
