php - PHPからMongoDBに保存されたJavaScript関数を呼び出す

Question

この関数を db.system.js に保存しています

function SomeFunc(o) {
    x = db.Collection;
    while( 1 ) {
        var c = x.find({},{_id:1}).sort({_id:-1}).limit(1);
        var i = c.hasNext() ? c.next()._id + 1 : 1;
        o._id = i;
        x.insert(o);
        var err = db.getLastErrorObj();
        if( err && err.code ) {
            if( err.code == 11000 /* dup key */ )
                continue;
            else
                print("unexpected error inserting data: " + tojson(err));
        }
        break;
    }
}

PHPで

print_r(
    $db->execute("SumeFunc(o)", array("name" => "test"))
);
