mongodb - How to return JSON data from php MongoCursor

Question

I am using PHP to connect with MongoDB. My code is as follows.

// connect
$m = new MongoClient($con_string); // connect to a remote host at a given port
$db = $m->main;

$customers = $db->customer->find();

i want to return $customers collection as json document to my HTML. How can i do this?

You can do this two ways:

echo json_encode(iterator_to_array($customers));

or you can manually scroll through it:

foreach($customers as $k => $row){
    echo json_encode($row);
}

Each of MongoDBs objects should have their __toString() methods correctly implemented to bring back the representation of the value.
