MongoDB Driver for PHP
PHP is one of the computer languages for which MongoDB has official drivers to make database interaction easier. Developers may utilise MongoDB as the only interface to their data with ease and productivity thanks to these drivers’ clear, language-sensitive API. These drivers will be used mainly by your application code, however the MongoDB shell is great for administration and experimentation.
This is an in-depth tutorial on how to use the PHP driver for MongoDB:
Installation
Setting up You will require the MongoDB PHP driver in order to use MongoDB with PHP. Your operating system has a little impact on the installation process:
Unix-Based Platforms (e.g., Ubuntu, Linux)
- Automatic Installation (PECL): PHP’s extension repository has the easiest installation method. Pecl install mongo installs the MongoDB extension if PECL is installed.
- Manual Installation: If PECL isn’t available, get the package from GitHub (e.g., mongodb-mongdb-php-driver-.tar.gz), unzip it, move to the directory, and compile using phpize,./configure, and sudo make install.
- Configuration: PHP must be told to load the driver after installation (either way). Open php.ini (php -i | grep Configuration) and add extension=mongo.so to the extensions section. For Apache HTTPd, sudo /etc/init.d/apache2 restart is needed to apply modifications.
Windows
- PHP driver precompiled binaries for Windows can be found on GitHub.
- PHP version, VC version, and thread-safety can be obtained in phpinfo() to find the correct package.
- Copy php_mongo.dll to PHP’s extension directory (Ext or Extensions) after downloading and extracting.
- Configuration: Place extension=php_mongo.dll in your php.ini file. For modifications to take effect, restart HTTP.
Confirming Installation
Verifying Installation To confirm that the PHP driver is loaded properly, make a PHP file with in it. Save it in the www directory of your web server (test.php, for example), and then launch it in a web browser. A section presenting MongoDB information should be shown; it should include the hostname, port, version number, and other information.
Connecting to MongoDB
Getting in touch with MongoDB After installing the driver, you can connect to your instance of MongoDB. This uses MongoClient (or Mongo in previous driver versions). Automatically construct the specified database if it doesn’t exist.
<?php
// connect to mongodb
$m = new MongoClient(); // Connects to localhost:27017 by default
echo "Connection to database successfully";
// select a database
$db = $m->mydb; // Selects or creates a database named 'mydb'
echo "Database mydb selected";
?>Altering the host and port is another option; for instance, $connection = new MongoClient(“example.com:12345”);. Although the driver handles closing connections when the Mongo object exits scope, it is often not required to do so manually, it is a good idea to call $connection->close();.
Basic CRUD Operations (Create, Read, Update, Delete)
CRUD (Create, Read, Update, Delete) Basic Operations For data manipulation, the PHP driver provides techniques similar to the shell commands:
- Create a Collection: createCollection() allows you to form a collection explicitly.
- Insert a Document: To add documents, use the insert() method. PHP represents documents as associative arrays.
- Find All Documents: The find() function gets documents, and a cursor can be used to iterate through the results.
- Update a Document: To make changes to an existing document, utilise the update() method. Usually, an update operator (such as $set) and query conditions are required.
- Delete a Document: Based on criteria, documents can be deleted using the remove() method.
BSON and Data Handling
Data Processing and BSON Formally, MongoDB documents are BSON documents, which are binary representations of JSON that also contain additional type information. Associative arrays, strings, numbers, and booleans are examples of PHP’s native data types that are automatically converted to and from BSON by the PHP driver. This implies that you usually interact with well-known PHP data structures, while the driver controls the underlying binary format for communication and storage. The superior performance and developer-friendliness of MongoDB are a result of this simplified methodology.
