With the release of PHP 8, many developers may encounter a common question, that is, how to add MySQL extensions in PHP 8. In this article, we will discuss how to use PHP Install and enable the MySQL extension in 8.

MySQL extension is a PHP extension for interacting with MySQL database. It allows developers to connect to the MySQL server and perform various database operations such as querying, inserting, updating, and deleting data.

In versions prior to PHP 8, the MySQL extension is enabled by default. However, since PHP version 7.0, the MySQL extension has been deprecated and replaced in PHP Completely removed in version 7.4. Instead, PHP introduces a new MySQLi extension (MySQL Improved), which provides better performance and more features.

While the MySQLi extension is a better choice, some projects may still rely on older MySQL extensions. In this case, we need to install and enable the MySQL extension manually.

Here are the steps to install and enable the MySQL extension in PHP 8:

Step 1: Install the MySQL client library

After installing the MySQL extension Before, we need to install the MySQL client library first. This is because the MySQL extension relies on these libraries to communicate with the MySQL server.

On Ubuntu, you can use the following command to install the MySQL client library:

sudo apt-get install mysql-client

On CentOS, you can use the following command to install the MySQL client library:

sudo yum install mysql

Step 2: Install the PHP 8 development tools

In order to be able to compile and install PHP extensions, we need to install the PHP 8 development tools. On Ubuntu, you can use the following command to install these tools:

sudo apt-get install php8.0-dev

On CentOS, you can use the following command to install these tools:

sudo yum install php8.0-devel

Step 3: Download the MySQL extension source Code

Next, we need to download the source code of the MySQL extension. The latest versions of MySQL extensions can be found on PECL (PHP Extensions Community Library).

In the terminal, use the following command to download the source code of the MySQL extension:

sudo pecl install mysql

Step 4: Compile and install the MySQL extension

After the download is complete , we need to enter the source code directory of the MySQL extension and use the following command to compile and install the MySQL extension:

cd mysql-
sudo phpize
sudo ./configure
sudo make
sudo make install

In the above command, replace `` with the version number of the MySQL extension.

Step 5: Enable MySQL extension

After the installation is complete, we need to enable the MySQL extension in the PHP configuration file. Open the php.ini file and add the following lines:

extension=mysql.so

Save and close the file.

Step 6: Restart the web server

Finally, we need to restart the web server for the changes to take effect. On Ubuntu, you can use the following command to restart the Apache server:

sudo service apache2 restart

On CentOS, you can use the following command to restart the Apache server:

sudo systemctl restart httpd

Now, the MySQL extension has been successfully installed and enabled. You can use functions such as `mysql_connect()` in PHP code to connect and operate the MySQL database.

Summary:

Adding MySQL extensions in PHP 8 requires some extra steps because MySQL extensions have been deprecated. First, install the MySQL client library and PHP 8 development tools.
