MongoCode::__constructCreates a new code object

Examples

Example #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);

?>

The above example will output something similar to:

 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; }" } 

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))));

?>
