What are the potential risks of not having the MySQL extension activated in PHP?

Without the MySQL extension activated in PHP, you will not be able to connect to MySQL databases and perform operations such as querying, inserting, updating, and deleting data. This can severely limit the functionality of your PHP applications that rely on database interactions. To solve this issue, you can activate the MySQL extension in your PHP configuration file (php.ini) by uncommenting or adding the following line: extension=mysqli.so

// Activate MySQL extension in PHP configuration file
extension=mysqli.so
