What is the difference between mysqli and PDO in PHP?

When it comes to database operations in PHP, there are two popular options: mysqli and PDO. The main difference between mysqli (MySQL Improved) and PDO (PHP Data Objects) lies in their usage and features.

mysqli:

mysqli is specifically designed to work with MySQL databases and offers a procedural and object-oriented interface. It provides options for prepared statements, transaction support, and improved security features compared to the older mysql extension.

PDO:

PDO is a database abstraction layer that provides a uniform interface for working with different databases, including MySQL, PostgreSQL, SQLite, and more. It supports prepared statements, transactions, and is object-oriented by nature, making it a more versatile choice compared to mysqli.

Overall, the choice between mysqli and PDO in PHP ultimately depends on the specific requirements of your project. If you need flexibility and portability across different database systems, PDO may be the better option. Alternatively, if you are primarily working with MySQL and seek improved security features, mysqli could be the suitable choice.
