copied!<p>I just posted a thorough solution to <a href="https://stackoverflow.com/questions/1082349/page-generation-from-php-class/1082470#1082470">another question</a> that is very closely-related to this question. I'll re-post it here for your convenience:</p> <hr> <p>I would suggest using some of the MVC (Model, View, Controller) frameworks out there like <a href="http://www.kohanaphp.com" rel="nofollow noreferrer">KohanaPHP</a>. It is essentially this. You're working in a strictly Object-Oriented environment. A simple page in Kohana, build entirely from a class would look like this:</p> <pre><code>class Home_Controller extends Controller { public function index() { echo "Hello World"; } } </code></pre> <p>You would then access that page by visiting youur url, the class name, and the method name:</p> <p><a href="http://www.mysite.com/home/" rel="nofollow noreferrer">http://www.mysite.com/home/</a> (<em>index() can be called after home/, but it's implicit</em>)</p> <p>When you start wanting to bring in database-activity, you'll start working with another Class called a <a href="http://docs.kohanaphp.com/general/models" rel="nofollow noreferrer">Model</a>. This will contain methods to interact with your database, like the following:</p> <pre><code>class Users_Model extends Model { public function count_users() { return $this->db->count_records('users'); } } </code></pre> <p>Note here that I didn't write my own query. Kohana comes with an intuitive <a href="http://docs.kohanaphp.com/libraries/database/builder" rel="nofollow noreferrer">Query Builder</a>.</p> <p>That method would be called from within your <a href="http://docs.kohanaphp.com/general/controllers" rel="nofollow noreferrer">Controller</a>, the first class that we mentioned at the beginning of this solution. That would look like this:</p> <pre><code>class Home_Controller extends Controller { public function index() { $usersModel = new Users_Model; $userCount = $usersModel->count_users(); echo "We have " . $userCount . " users!"; } } </code></pre> <p>Eventually, you'll want more complicated layouts, which will involve HTML/CSS/Javascript. At this point, you would introduce the "<a href="http://docs.kohanaphp.com/general/views" rel="nofollow noreferrer">Views</a>," which are just presentation layers. Rather than calling <code>echo</code> or <code>print</code> from within the Controller, you would load up a view (an HTML page, essentially) and pass it some variables:</p> <pre><code>class Home_Controller extends Controller { public function index() { $myView = new View("index"); $usersModel = new Users_Model; $userCount = $usersModel->count_users(); $myView->userCount = $userCount; $myView->render(TRUE); } } </code></pre> <p>Which would load the following "View"</p> <pre><code><p>We have <?php print $userCount; ?> users!</p> </code></pre> <p>That should be enough to get you started. Using the MVC-style is really clean, and very fun to work with.</p>

Querying!

An individual column

Larger individual text columns get their own page to allow for proper reading.
