   'databases' => array( 'default' => array( 'engine' => '\photon\db\MongoDB', 'server' => 'mongodb://localhost:27017/', 'database' => 'utils', 'options' => array( 'connect' => true, ), ), ),

Counters

The counter class implement a atomic counter increment and retreive. It's a thread safe auto-increment.

1. Create a class to define a counters collection

   class MyCounter extends \photon\utils\mongodb\Counter { const database = 'default'; const collection = 'counters'; }

2. Read / Write counter

    $value = MyCounter::get('foo');     // = 0
    $value = MyCounter::inc('foo');     // = 1
    $value = MyCounter::get('bar');     // = 0
    $value = MyCounter::get('foo');     // = 1
