MongoCode::__construct — Creates a new code object

### Descripción

`code`

  A string of code.

`scope`

  The scope to use for the code.

### Ejemplos

Example #1 MongoCode::__construct() example

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

El resultado del ejemplo seria algo similar a:

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

Example #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))));
?>`
