how to create and return the iterator for contact collection based on the the company_id.

Answer 1

The default result of a find() is a MongoCursor .. aka an iterator :).

<?php
    // Connect to MongoDB server
    $mongo = new Mongo();

    // Use database 'mydb' and collection 'contacts'
    $collection = $mongo->mydb->contacts;

    $cursor = $collection->find(array('company_id' => $company_id));

    // $company = $cursor->getNext();

    //  .. or .. 

    // foreach ($cursor as $company) {
        // ..
    // }
?>
