Study Notes
What is PHP PDO?
- PHP PDO is an extension that provides a consistent interface for accessing databases in PHP.
- It supports various database management systems, such as MySQL, PostgreSQL, SQLite, etc.
- PDO offers a secure and flexible way to interact with databases, promoting best practices like prepared statements and parameter binding.
Key Benefits of PDO
- Simplifies database interaction by offering a unified API across different database systems.
- Enhances security by supporting prepared statements and parameterized queries, reducing the risk of SQL injection attacks.
- Promotes code portability, allowing developers to switch between databases with minimal code changes.
