PHP & MongoDB – Quick Guide
PHP & MongoDB – Overview
PHP developer team has provided MongoDB Driver for PHP and have various resources available for it.
First step in connecting to MongoDB using PHP is to have mongodb PHP driver dll in php ext directory and enable it in php.ini and then use mongodb API to connect to the database.
Connecting to MongoDB database
Suppose, MongoDB is installed locally and using default port then following syntax connects to MongoDB database.
$manager = new MongoDBDriverManager("mongodb://localhost:27017");
MongoDB Driver Manager is the central class to do all the operations on mongodb database. To connect to mongodb database, we connect to database by first preparing a command and then executing it.
$statistics = new MongoDBDriverCommand(["dbstats" => 1]);
$cursor = $manager->executeCommand("mydb", $statistics);
Once command is executed, if mydb database is not present, it will be created otherwise, it will be connected.
PHP & MongoDB – Environment Setup
Install MongoDB database
Follow the MongoDB installation steps using
Install PHP
Follow the PHP installation steps using
PHP MongoDB Driver
To use MongoDB with PHP, you need to use MongoDB PHP driver. Download the driver from the url . 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 following line to your php.ini file −
extension = php_mongo.dll
In case of Windows, make sure libsasl.dll is in the windows”s PATH. This dll is available in PHP installation directory.
PHP & MongoDB – Connecting Database
First step to do any operation is to create a Manager instance.
// Connect to MongoDB using Manager Instance
$manager = new MongoDBDriverManager("mongodb://localhost:27017");
Second step is to prepare and execute a command on a database if the database doesn”t exist then MongoDB creates it automatically.
// Create a Command Instance
$statistics = new MongoDBDriverCommand(["dbstats" => 1]);
// Execute the command on the database
$cursor = $manager->executeCommand("myDb", $statistics);
Example
Try the following example to connect to a MongoDB server −
Copy and paste the following example as mongodb_example.php −
<?php
try {
// connect to mongodb
$manager = new MongoDBDriverManager("mongodb://localhost:27017");
echo "Connection to database successfully";
$statistics = new MongoDBDriverCommand(["dbstats" => 1]);
$cursor = $manager->executeCommand("myDb", $statistics);
$statistics = current($cursor->toArray());
echo "<pre>";
print_r($statistics);
echo "</pre>";
} catch (MongoDBDriverExceptionException $e) {
echo "Exception:", $e->getMessage(), "n";
}
?>
Output
Access the mongodb_example.php deployed on apache web server and verify the output.
Connection to database successfully stdClass Object ( [db] => myDb [collections] => 0 [views] => 0 [objects] => 0 [avgObjSize] => 0 [dataSize] => 0 [storageSize] => 0 [totalSize] => 0 [indexes] => 0 [indexSize] => 0 [scaleFactor] => 1 [fileSize] => 0 [fsUsedSize] => 0 [fsTotalSize] => 0 [ok] => 1 )

Example
Try the following example to list databases available by default in MongoDB server −
Copy and paste the following example as mongodb_example.php −
<?php
try {

$manager = new MongoDBDriverManager("mongodb://localhost:27017");
// Create a Command Instance
$databaseList = new MongoDBDriverCommand(["listDatabases" => 1]);
// Execute the command on the database
$cursor = $manager->executeCommand("admin", $databaseList);
$databases = current($cursor->toArray());
foreach ($databases->databases as $database) {
echo $database->name . "<br/>";

}
?>
Output
Access the mongodb_example.php deployed on apache web server and verify the output.
