MySQL, MySQLi, or PDO: Which PHP Database Extension Should You Choose?

Understanding the Differences: MySQL, MySQLi, and PDO for PHP-MySQL Interactions

When it comes to working with PHP and MySQL, developers have multiple options at their disposal. Three common approaches are MySQL, MySQLi, and PDO. Understanding their distinctions is crucial for selecting the optimal tool for your project.

MySQL: Procedural and Deprecated

The MySQL functions represent the procedural approach to MySQL database interactions. This method employs manual escaping, which requires developers to manually sanitize user input to prevent SQL injections. However, the MySQL functions are considered deprecated and should not be used in new projects.

MySQLi: Object-Oriented and Procedural

MySQLi serves as a replacement for the MySQL functions, offering both object-oriented and procedural interfaces. It introduces support for prepared statements, which are essential for preventing SQL injections and improving performance. Prepared statements involve binding parameters to queries, eliminating the need for manual escaping.

PDO: Database Abstraction Layer

PDO (PHP Data Objects) provides a database abstraction layer that supports not only MySQL but also numerous other database systems. It features prepared statements as well. PDO offers greater flexibility in how data is returned, including the ability to retrieve data as objects, arrays, or JSON.

Recommendation: PDO for Security, Flexibility, and Scalability

For modern PHP-MySQL development, PDO is the recommended choice. It combines the benefits of prepared statements for security and performance with the flexibility to work with various databases. PDO also provides a convenient and well-designed API that facilitates database interactions.
