This document discusses PHP development with MongoDB. It covers installing and connecting to MongoDB from PHP, performing queries, using datatypes like MongoDate and MongoId, and best practices for insertion and removal of documents. The slides provide an overview of using MongoDB with PHP for tasks like server monitoring and storing large amounts of data.

$serversCollection = $mongo->selectCollection(‘servers’);
$server = $serversCollection->findOne(array(‘os’ =>
‘windows’), array(‘_id’, ‘name’, ‘ip’));

17. MongoDate
MongoDB Equivalent
new MongoDate() time()
new MongoDate(strtotime(‘now’)) time()
17/24

18. MongoDate
$from = new MongoDate(strtotime(‘2010-06-18 00:00:00’));
$to = new MongoDate(strtotime(‘2010-06-18 23:59:59’));
$collection->find(array(‘added’ => array('$gt' => $from,
'$lte' => $to)));
18/24

19. MongoId
$doc = $collection->findOne(array(‘_id’ =>
‘4b74ae0d064b35442948da4c’));
19/24

20. MongoId
$id = new MongoId(‘4b74ae0d064b35442948da4c’);
$doc = $collection->findOne(array(‘_id’ => $id));
20/24

21. MongoId & remove()
Slow(er):
$collection->remove(array(‘key1’ => 5, ‘key2’ => 6));
Fast(er):
$cursor = $collection->find(array(‘key1’ => 5, ‘key2’
=> 6));
$while ($cursor->hasNext())
{
$item = $cursor->getNext();
$key = new MongoId($cursor->key());
$collection->remove(array('_id' => $key));
}

22. Safe insert()
$collection->insert($doc, array(‘safe’));
