Beispiele
Beispiel #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);
?>
Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:
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; }"
}
Beispiel #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))));
?>
