To use MongoDB with PHP, you need to use MongoDB PHP driver. Download the driver from the url Download PHP Driver. Make sure to download the latest release of it. Now unzip the archive and put php_mongo.dll in your PHP extension directory (“ext” by default) and add the subsequent line to your php.ini file −
extension = php_mongo.dll

Make a Connection and Select a Database

To make a connection, you need to specify the database name, if the database doesn’t exist then MongoDB creates it automatically.
Subsequent is that the code snippet to connect to the database −
<?php
// connect to mongodb
$m = new MongoClient();

echo “Connection to database successfully”;
// select a database
$db = $m->mydb;

echo “Database mydb selected”;
?>
When the program is executed, it will produce the subsequent result −
Connection to database successfully
Database mydb selected

Create a Collection

Subsequent is that the code snippet to create a collection −
<?php
// connect to mongodb
$m = new MongoClient();
echo “Connection to database successfully”;

// select a database
$db = $m->mydb;
echo “Database mydb selected”;
$collection = $db->createCollection(“mycol”);
echo “Collection created succsessfully”;
?>
When the program is executed, it will produce the subsequent result −
Connection to database successfully
Database mydb selected
Collection created succsessfully

Insert a Document

To insert a document into MongoDB, insert() method is employed.
Subsequent is that the code snippet to insert a document −
<?php
// connect to mongodb
$m = new MongoClient();
echo “Connection to database successfully”;

// select a database
$db = $m->mydb;
echo “Database mydb selected”;
$collection = $db->mycol;
echo “Collection selected succsessfully”;

$document = array(
“title” => “MongoDB”,
“description” => “database”,
“likes” => 100,
“url” => “http://www.tecklearn.com/mongodb/”,
“by” => “tecklearn”
);

$collection->insert($document);
echo “Document inserted successfully”;
?>
When the program is executed, it will produce the subsequent result −
Connection to database successfully
Database mydb selected
Collection selected succsessfully
Document inserted successfully

Find All Documents

To select all documents from the collection, find() method is employed.
Subsequent is that the code snippet to select all documents −
<?php
// connect to mongodb
$m = new MongoClient();
echo “Connection to database successfully”;

// select a database
$db = $m->mydb;
echo “Database mydb selected”;
$collection = $db->mycol;
echo “Collection selected succsessfully”;

$cursor = $collection->find();
// iterate cursor to display title of documents

Update a Document

To update a document, you need to use the update() method.
In the subsequent example, we will update the title of inserted document to MongoDB Tutorial. Subsequent is that the code snippet to update a document −
<?php
// connect to mongodb
$m = new MongoClient();
echo “Connection to database successfully”;

// select a database
$db = $m->mydb;
echo “Database mydb selected”;
$collection = $db->mycol;
echo “Collection selected succsessfully”;

// now update the document
$collection->update(array(“title”=>”MongoDB”),
array(‘$set’=>array(“title”=>”MongoDB Tutorial”)));
echo “Document updated successfully”;

// now display the updated document
$cursor = $collection->find();

// iterate cursor to display title of documents
echo “Updated document”;

Delete a Document

To delete a document, you need to use remove() method.
In the subsequent example, we will remove the documents that has the title MongoDB Tutorial. Subsequent is that the code snippet to delete a document −
<?php
// connect to mongodb
$m = new MongoClient();
echo “Connection to database successfully”;

// select a database
$db = $m->mydb;
echo “Database mydb selected”;
$collection = $db->mycol;
echo “Collection selected succsessfully”;

// now remove the document
$collection->remove(array(“title”=>”MongoDB Tutorial”),false);
echo “Documents deleted successfully”;

// now display the available documents
$cursor = $collection->find();

// iterate cursor to display title of documents
echo “Updated document”;

foreach ($cursor as $document) {
echo $document[“title”] . “\n”;
}
?>
When the program is executed, it will produce the subsequent result −
Connection to database successfully
Database mydb selected
Collection selected succsessfully
Documents deleted successfully
In the above example, the second parameter is boolean type and employed for justOne field of remove() method.
Remaining MongoDB methods findOne(), save(), limit(), skip(), sort() etc. works same as explained above.
