PHP & MongoDB – Quick Guide ”; Previous Next 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 MongoDB – Environment Setup Install PHP Follow the PHP installation steps using PHP 7 – Environment Setup PHP MongoDB Driver 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 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.
