    <p>I think you're looking for the <a href="http://ca.php.net/include_once" rel="nofollow"><code>include_once</code></a> function. Essentially, you want to have each of your classes in their own separate file, and then when you want to use them, you call <code>include_once("thatfile.php");</code> to make that class accessible to your application.</p> <p>I should clarify that you should use <code>include_once</code> (or <a href="http://ca.php.net/require_once" rel="nofollow"><code>require_once</code></a> if you would prefer) over <code>include</code> because if you include your class file twice, you'll get errors saying you're trying to define a class that already exists.</p> <p>Using your example, your program would look like this:</p> <p><strong>MessageClass.php</strong></p> <pre><code>&lt;?php class Message { public $message; // Return a string containing a list of messages found public function listMessages($delim = ' '){ if (count($this-&gt;message) &gt; 0){ echo implode($delim,$this-&gt;message); }else{ return false; } } // Manually add Message public function addMessage($description){ $this-&gt;message[] = $description; } } </code></pre> <p><strong>index.php</strong></p> <pre><code>&lt;?php include_once("MessageClass.php"); $message = new Message(); $message-&gt;addMessage('Article Title 1'); $message-&gt;addMessage('Article Title 2'); $message-&gt;listMessages(); </code></pre> <p>Also notice that I changed your class variables (members) and functions (methods) to include the <code>public</code> modifier. I'm not 100% sure about how it works in PHP, but in most languages these things tend to be <code>private</code> by default, meaning they can't be accessed from outside of the class. It's always better to include them to be clear.</p> <p>You might also want to look into the <a href="http://ca.php.net/__autoload" rel="nofollow"><code>__autoload()</code></a> function, which is called whenever you try to use a class which hasn't yet been defined. In this function, which you define yourself, you can figure out in which file a given class resides, and <code>include_once</code> it automatically when you need it. More generally, you should look into the <a href="http://ca.php.net/manual/en/function.spl-autoload-register.php" rel="nofollow"><code>spl_autoload_register</code></a> function, which is the same thing but with a lot more flexibility.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
