Warning

This extension is deprecated. Instead, the MongoDB extension should be used.

This is the official MongoDB driver for PHP.

Here's a quick code sample that connects, inserts documents, queries for documents, iterates through query results, and disconnects from MongoDB. There are more details on each step in the tutorial below.

`<?php
// connect
$m = new MongoClient();
// select a database
$db = $m->comedy;
// select a collection (analogous to a relational database's table)
$collection = $db->cartoons;
// add a record
$document = array( "title" => "Calvin and Hobbes", "author" => "Bill Watterson" );
$collection->insert($document);
// add another record, with a different "shape"
$document = array( "title" => "XKCD", "online" => true );
$collection->insert($document);
// find everything in the collection
$cursor = $collection->find();
// iterate through the results
foreach ($cursor as $document) {
echo $document["title"] . "\n";
}
?>`

The above example will output:

    Calvin and Hobbes
    XKCD
