Batch insertion is a quick way to add many elements to the database at once

<?php

$users 
= array();
for (
$i 0$i<100$i++) {
  
$users[] = array('username' => 'user'.$i'i' => $i);
}

$mongo = new Mongo();
$collection $mongo->my_db->users;
$collection->drop();

$collection->batchInsert($users);

foreach (
$users as $user) {
  echo 
$user['_id']."\n"// populated with instanceof MongoId
}

$users $collection->find()->sort(array('i' => 1));
foreach (
$users as $user) {
    
var_dump($user['username']);
}
