Globals overwrite and its consequences

[arborint]

Perhaps a best practice would be to always use something like:

class Global {

function get($key) {
    return $GLOBALS[$var];
}

function set($key, $value = null) {
    $GLOBALS[$key] = $value;
}

function has($key) {
    return isset($GLOBALS[$key]);
}

} 

Look familiar?

Perhaps a best practice would be to always use something like:

class Global {

function get($key) {
    return $GLOBALS[$var];
}

function set($key, $value = null) {
    $GLOBALS[$key] = $value;
}

function has($key) {
    return isset($GLOBALS[$key]);
}

} 

Or even:

class Global
{
    private static $instance;
    private $values;

    private function __construct()
    {
    }

    public static function instance()
    {
        if(empty(self::$instance)) {
            self::$instance = new self();
        }
        return self::$instance;
    }

    public function __get($key)
    {
        return isset(self::instance()->values[$key]) ? self::instance()->values[$key] : null;
    }

    public function __set($key, $value = null)
    {
        if(is_null($value)) {
            if(isset(self::instance()->values[$key])) {
                unset(self::instance()->values[$key]);
            }
        }
        else {
            self::instance()->values[$key] = $value;
        }
    }

    public static function get($name)
    {
        return self::instance()->__get($name);
    }

    public static function set($name, $value = null)
    {
        self::instance()->__set($name, $value);
    }

} 

Look familiar?

Not really...
