### Przykłady

Przykład #1 MongoCode::__construct() example

`<?php
$code = new MongoCode('function() { '.
'for(i=0;i<10;i++) {'.
'db.foo.update({z : i}, {z : x});'.
'}'.
'return x-1;'.
'}', array("x" => 4));
var_dump($code);
?>`

Powyższy przykład wyświetli coś podobnego do:

    object(MongoCode)#1 (2) {
      ["scope"]=>
      array(1) {
        ["x"]=>
        int(4)
      }
      ["code"]=>
      string(80) "function() { for(i=0;i<10;i++) { db.foo.update({z : i}, {z : x}); } return x-1; }"
    }

Przykład #2 Using MongoCode with $where

This example queries a collection for elements where the 'x' fields is less than $y. Notice that PHP objects can be passed into the JavaScript scope and that the JavaScript function returns a boolean.

`<?php
$cursor = $collection->find(array('$where' => new MongoCode('function() { return this.x < y; }', array('y'=>$y))));
?>`
