Answer 3

Example using jQuery. Note this is but one of 1000 ways to do this. This just outlines the basic idea of the process of building a table using AJAX and Laravel. It's not meant to be a drop-in code segment.

Basic table code

<table id="example" class="table">
    <thead>
        <tr class="headings">
            <th>ID &nbsp;&nbsp;&nbsp;</th>
            <th>first name </th>
            <th>last name </th>
            <th>E-mail </th>
            <th>birthday </th>
        </tr>
    </thead>

    <tbody>
        <?php // empty for now ?>
    </tbody>
</table>

tablecontents.blade.php

<?php // Requires the $users table ?>
@foreach ($users as $user)
     <tr class="even pointer">
         <td class=" ">{{ $user->id }}</td>
         <td class=" ">{{ $user->name }}</td>
         <td class=" ">{{ $user->name2 }}</td>
         <td class=" ">{{ $user->email }}</td>
         <td class=" ">{{ $user->birthday }}</td>
     </tr>
@endforeach

AjaxController.php (or similar)

function getUpdatedTable() {
     $users = //get users
     return view("tablecontents", [ "users", $users ]);
} 

JavaScript

function updateTable() {
    $.ajax({
        url: "ajax/getUpdatedTable",
        success: function (data) {
             $("#example tbody").html(data);
        }

    });
}

$(document).ready(function () { 
     updateTable();
     setInterval(updateTable, 5000); //Re-update every 5 seconds     
});

Like mentioned inside the comments, you can use frameworks like jQuery to build a real-time module.

$( document ).ready( function () {
    $.get('generic-handler.php')
        .done( function (data) {
            $('#realtime').innerHTML = data;
        });
});

Inside your PHP file you put your code to display the database and then you can wrap it in a setInterval so your request is sent every X number of seconds.
