    <p>If I really wanted to do something like that, I'd use a static array instead:</p> <pre><code>function set($key, $value, $default = null) { static $values = array(); $values[$key] = is_null($value) ? $default : $value; } </code></pre> <p>If you want to also be able to access this data, a better idea is to encapsulate it in a class.</p> <pre><code>class Registry { private static $values = array(); public static function set($key, $value, $default = null) { self::$values[$key] = is_null($value) ? $default : $value; } public static function get($key, $default = null) { return array_key_exists($key, self::$values) ? self::$values[$key] : $default; } } </code></pre> <p>Then you can use the class statically:</p> <pre><code>Registry::set('key', 'value', 'default'); $value = Registry::get('key', 'default'); </code></pre> <p>An even better way of doing this is to not use the <code>static</code> keyword at all, and instead make a normal class with normal properties, then make a single instance of it and use that instance.</p> <pre><code>class Registry { private $values = array(); public function set($key, $value, $default = null) { $this-&gt;values[$key] = is_null($value) ? $default : $value; } public function get($key, $default = null) { return array_key_exists($key, $this-&gt;values) ? $this-&gt;values[$key] : $default; } } </code></pre> <p>You can then make an instance of the class and pass it along:</p> <pre><code>$registry = new Registry(); do_something_that_requires_the_registry($registry); </code></pre>

    2. CO@LFS, how do you plan to access these variables after you set them inside a static variable in the `set()` function?

    3. CODamn.. I am beginning to think that I misunderstood completely the workings of the static keyword.. Now I want to remove my question, as it might not make any sense..

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
