This repository contains a simple web application that demonstrates how to quickly connect to and communicate with a MariaDB database using PHP and PDO (PHP Data Objects).
⚠️ Interested in using MariaDB and PHP with mysqli? Check out the quickstart here!
The application in this repository demonstrates how to:
- Connect to a MariaDB database using PDO (PHP Data Objects)
- Execute queries (
SELECT,UPDATE,INSERTandDELETE) to manage contact data (like a digital rolodex) - Use prepared statements
The application relies on a single database (rolodex) that contains a single table (contacts). You can find the necessary SQL for setting up the environment in schema.sql.
After you've pulled down this repository, follow these steps to get the app up and running:
-
Update the database configuration settings in src/config.php (which is used across the app) to point to your MariaDB database.
Example configuration:
$dsn = "mysql:host=127.0.0.1;dbname=rolodex;charset=utf8mb4"; $options = [ PDO::ATTR_EMULATE_PREPARES => false, // Disable emulation mode for "real" prepared statements PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION, // Disable errors in the form of exceptions PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC, // Make the default fetch be an associative array ]; $pdo = new PDO($dsn, "app_user", "Password123!", $options);
-
Within the src directory, run the application using the built-in web server.
$ php -S localhost:5000
