This example shows how mongo_has_next can be used to iterate through results.


<?php

$conn = mongo_connect("localhost", true);
if (!$conn) {
   die("Could not connect.");
}
$cursor = mongo_query($conn, "foo.bar", array(), 0, 0, null, null, null);
while (mongo_has_next($cursor)) {
   mongo_next($cursor);
   echo "."
