copied!<p>In your question you say you have a multidimensional array, so I take it is like this:</p> <pre><code>$config = array('foo' => array('bar' => array('baz' => 3))); </code></pre> <p>Calling <code>item('foo', 'bar', 'baz')</code> would run all the way through to the last array and return 3. If that is what you want, you could just write <code>$config['foo']['bar']['baz']</code> or place your configs in an <a href="http://de.php.net/manual/en/class.arrayobject.php" rel="nofollow noreferrer">ArrayObject</a> and use either the array access notation or <code>$config->foo->bar->baz</code> (though all nested arrays must be ArrayObjects too then). </p> <p>If you want to keep the function, you should add some checking on the index before you grab it, because PHP will raise a Notice about undefined indexes. In addition, why not use <a href="http://de.php.net/manual/en/class.invalidargumentexception.php" rel="nofollow noreferrer">InvalidArgumentException</a> instead of Exception. Fits better for this case.</p> <p><em>edit: removed some portion of the answer, because it was more like loud thinking</em></p> <p><em>edit after comments</em><br/> Tbh, I find it a rather awkward approach to reinvent array access through a method like this. In my opinion you should either pass the entire config or a subset to your objects during construction and let them take whatever they need through the regular array accessors. This will <a href="http://en.wikipedia.org/wiki/Dependency_inversion_principle" rel="nofollow noreferrer">decouple</a> your objects from your configManager and allows for easier modification at a later point.</p>
