Which PHP-MySQL Interface is Best: MySQL, MySQLi, or PDO?

Understanding the Differences Between MySQL, MySQLi, and PDO for PHP-MySQL

When working with PHP and MySQL, it's essential to understand the differences between the three common interfaces available: MySQL, MySQLi, and PDO. Each interface offers its own set of features and advantages, making it crucial to choose the most appropriate one for your project.

MySQL

MySQL is the original interface for PHP-MySQL. It provides basic functions for connecting to the database and executing queries. However, this interface is considered deprecated due to its security vulnerabilities and lack of modern features. Manual escaping is used for protecting data from SQL injection.

MySQLi

MySQLi is the improved version of MySQL, offering both procedural and object-oriented styles. It introduces several security enhancements and supports prepared statements. Prepared statements help prevent SQL injection by separating query parameters from the query itself, making it more secure.

PDO

PDO (PHP Data Objects) is a general database abstraction layer that supports MySQL and many other database systems. It provides a consistent interface for interacting with different database drivers. Prepared statements are supported in PDO as well, but it also offers flexibility in how data is returned.

Recommendation for PHP-MySQL

When selecting an interface for PHP-MySQL, PDO is generally the recommended choice. PDO provides a modern and well-designed API with strong security measures and support for multiple database systems. Prepared statements should be used for security reasons, and PDO makes it easy to switch to another database if needed.
