    <p>After some playing around the best method I can think of is like so:</p> <p>Create a file called SingletonBase.php and include it in root of your script!</p> <p>The code is</p> <pre><code>abstract class SingletonBase { private static $storage = array(); public static function Singleton($class) { if(in_array($class,self::$storage)) { return self::$storage[$class]; } return self::$storage[$class] = new $class(); } public static function storage() { return self::$storage; } } </code></pre> <p>Then for any class you want to make a singleton just add this small single method.</p> <pre><code>public static function Singleton() { return SingletonBase::Singleton(get_class()); } </code></pre> <hr> <p>Here is a small example:</p> <pre><code>include 'libraries/SingletonBase.resource.php'; class Database { //Add that singleton function. public static function Singleton() { return SingletonBase::Singleton(get_class()); } public function run() { echo 'running...'; } } $Database = Database::Singleton(); $Database-&gt;run(); </code></pre> <p>And you can just add this singleton function in any class you have and it will only create 1 instance per class.</p> <p>Just another idea you can also do</p> <pre><code>if(class_exists('Database')) { $Database = SingletonBase::Singlton('Database'); } </code></pre> <hr> <p>and at the end of your script you can do some dfebugging if you need too,</p> <p>at the end of your script you can just do</p> <pre><code>foreach(SingletonBase::storage () as $name =&gt; $object) { if(method_exists("debugInfo",$object)) { debug_object($name,$object,$object-&gt;debugInfo()); } } </code></pre> <p>so this method will be great for a debugger to get access to all classes and object states that have been initialized </p>

    1. COGood idea, something I hadn't thought about. However, this really doesn't answer my question.

    2. COyour question was answered by many other people in regards with that you cant call it a singleton because your creating a new instance every time, My code was to show you how you can be clean, small amount of coding, and acts as a true singleton, witch in fact it does answer parts of your question :)

    3. COThis doesn't create a singleton because you can still call 'new Database();'

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.
