Learn moreĪnd if you’d like to learn even more about what’s possible with MariaDB, be sure to check out the Developer Hub and our new Developer Code Central GitHub organization. If you’d like to see for yourself what else is possible with PHP and MariaDB, start by checking out the full source code for the Rolodex application in the new PHP Quickstart GitHub repository. $stmt->bind_param("sisi", $name, $age, $email, $id) ĭeleting data $stmt = $mysqli->prepare("DELETE FROM contacts WHERE id=?") Īs you can see, getting started with PHP and MariaDB is easy, but we’ve only scratched the surface of what’s possible. Updating data $stmt = $mysqli->prepare("UPDATE contacts SET name=?, age=?, email=? WHERE id=?") $stmt->bind_param("sis", $name, $age, $email) Inserting data $stmt = $mysqli->prepare("INSERT INTO contacts (name,age,email) VALUES(?, ?, ?)") ![]() Or, in the case that you need to handle dynamically inserted parameter values, you can use mysqli_prepare. Then, with an established connection, you have the ability to use a plethora of capabilities from the mysqli extension, including executing queries using mysqli_query. Using, and reusing, the mysqli connection within config.php is as easy as including it within a PHP code block on another PHP page. Within the config.php file I’ve started by defining variables that hold the host address, username, password and default database that are used to create a new mysqli connection object, which contains a variety of configuration options that you can use to tailor to your environment. $mysqli = mysqli_connect($databaseHost, $databaseUsername, $databasePassword, $databaseName) Connecting to and communicating with an underlying MariaDB database is facilitated by the mysqli PHP extension. To facilitate the use of a MariaDB database within the Rolodex PHP application I’ve created a new file called config.php that contains the configuration settings and database connection object that can be reused across PHP pages. The SQL necessary to run the Rolodex application can be found in the schema.sql file. The rolodex database contains a single table, contacts, that is used to store basic information. Preparing the databaseīefore jumping into the PHP code for the application it’s important to note that it uses a single database called rolodex. Everything I’ll be exploring is based on the code for the Rolodex application, and if you’d like to dive into the code you can check it out here. In this article I’m going to highlight, from a high level, some of the fundamental details of using PHP to connect to and communicate with a MariaDB database. So to demonstrate this, I’ve created a simple PHP web application called Rolodex to manage contacts. ![]() Like many other languages, PHP has the ability to take advantage of the power of MariaDB, and it’s actually a pretty simple and straightforward process.īut talk (or text in this case) is cheap. In fact, that’s as true now as it has ever been as the past few versions of PHP have made the language more appealing than ever. Find the CSS for this project in the GitHub repository, along with the other simple PHP website code.The PHP programming language has long been considered a fairly light and simple solution for developers to use to create robust and creative web applications. Use CSS to position and style it, as you would with any other element. For example, a lower-case "y" would display the year in two-digit format, rather than four. You can change how this is displayed by referring to the official PHP documentation. Notice how the echo date("Y") statement displays the current year in four digits. This will appear in the index.php file following the footer. Include a copyright notice, with an always-updated year: Copyright © CM Cawley Keep in mind that the actual PHP file you have open in your browser consists of just three lines.įinally, you can add a little PHP flourish with the final line. You should see the completed web page in your browser. Save, upload to your server, then browse to index.php. With three separate HTML files in /html/ you can use PHP echo to compile them into a single page.Ĭreate a new PHP file called index.php with the following three lines in it: ![]()
