MongoCode::__construct — Creates a new code object
A string of code.
The scope to use for the code.
Returns a new code object.
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);
?>
위 예제의 출력 예시:
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))));
?>
