    <p>Ok so i have the following code setup which seems to work fine:</p> <p>user handler "module":</p> <pre><code>class user_handler { private $dbo; public function __construct($dbo) { $this-&gt;dbo = $dbo; } public function user_table_method() { $this-&gt;dbo-&gt;generic_db_method(); } } </code></pre> <p>the connection class:</p> <pre><code>class connection { private $dbc; public $user; public function __construct() { $this-&gt;dbc = 'connection'; $this-&gt;user = new user_handler($this); } public function generic_db_method() { echo '&lt;p&gt;doing stuff with ' . $this-&gt;dbc . '&lt;/p&gt;'; } } </code></pre> <p>Then i can access user handler methods like so:</p> <pre><code>$dbc = new connection(); $dbc-&gt;user-&gt;user_table_method(); </code></pre> <p><strong>My question is this:</strong></p> <p>Would it be possible with a method in the <code>connection</code> class to create the <code>_user</code> object only when it's required?</p> <p>What i'm thinking of is a method that would be used like so:</p> <pre><code>$dbc-&gt;add_handle('user', 'user_handler'); </code></pre> <p>Which would create a new public property called <code>user</code> from scratch and set it as a new <code>user_handler</code> object:</p> <pre><code>// in more detail public function add_handle($name, $module) { if(!isset($this-&gt;/*somehow use $name*/)) { $this-&gt;/*somehow use $name*/ = new /*somehow use $module*/(); } } </code></pre> <p>..so the new way to set it up would be like:</p> <pre><code>$dbc = new connection(); $dbc-&gt;add_handle('user', 'user_handler'); $dbc-&gt;user-&gt;user_table_method(); </code></pre> <p>Thanks in advance! (looking at php 5.2 and up)</p>

    1. COYou should not start your public variables or methods with an underscore. That is confusing, man.

    3. CONaming methods or properties starting with an underscore is generally for private methods or properties, not public. See http://pear.php.net/manual/en/standards.naming.php

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.
