How to Create a MariaDB Connect in PHP for WordPress

In this blog post, we will explore the process of creating a MariaDB connect in PHP for your WordPress website. Connecting to a MariaDB database is essential for many WordPress applications, and PHP provides robust functionalities to establish a connection. Let’s dive in!

Step 1: Install the MariaDB Extension

Before you can connect to a MariaDB database, you need to ensure that the necessary extension is installed in your PHP environment. You can do this by following these steps:

  1. Open your terminal or command prompt.
  2. Type the following command: sudo apt-get install php-mysql
  3. Press Enter to execute the command.

This command will install the MariaDB extension for PHP, allowing you to establish a connection.

Step 2: Create Database Credentials

Next, you need to gather the necessary information to connect to your MariaDB database. You will need the following details:

  • Database host
  • Database name
  • Database username
  • Database password

Make sure you have these credentials handy as you proceed to the next step.

Step 3: Establish the Connection

Now that you have the MariaDB extension installed and your database credentials ready, it’s time to establish the connection in PHP. Here’s an example code snippet:

$mysqli = new mysqli("localhost","my_user","my_password","my_db");

// Check connection
if ($mysqli -> connect_errno) {
  echo "Failed to connect to MySQL: " . $mysqli -> connect_error;

Make sure to replace the placeholder values with your actual database credentials. The mysqli object is used to establish the connection, and the connect_errno property is checked to ensure the connection was successful.

Step 4: Perform Database Operations

Once the connection is established, you can perform various database operations using PHP. Here are a few examples:

  • Select data from a table: You can use SQL queries with the mysqli->query() method to retrieve data from your database.
  • Insert data into a table: Use the mysqli->query() method to execute an INSERT statement and add data to your database.
  • Update data in a table: Use the mysqli->query() method with an UPDATE statement to modify existing data.
  • Delete data from a table: Use the mysqli->query() method with a DELETE statement to remove data from your database.

These are just a few examples of the database operations you can perform using PHP.


Creating a MariaDB connect in PHP for your WordPress website is an essential skill. By following the steps outlined in this blog post, you can establish a connection to your MariaDB database and perform various database operations using PHP. Remember to always handle your database credentials securely and sanitize user inputs to prevent SQL injection attacks.
