Description: MySQLi, which stands for ‘MySQL Improved’, is a PHP extension that provides an object-oriented interface for interacting with MySQL databases. This extension was designed to overcome the limitations of the old MySQL extension, offering advanced features such as support for transactions, prepared statements, and better error handling. MySQLi allows developers to leverage MySQL’s capabilities more efficiently and securely, facilitating the creation of dynamic web applications. Among its most notable features are the ability to connect to databases securely using SSL-based authentication, as well as the option to work in both an object-oriented style and a procedural style. This provides flexibility to programmers, allowing them to choose the approach that best suits their needs. MySQLi is widely used in web application development, especially in conjunction with various PHP frameworks, and is essential for those looking to build robust and scalable applications that require efficient data management.
History: MySQLi was introduced in PHP 5, released in July 2004, as a response to the limitations of the old MySQL extension. The need for a more secure and efficient interface for interacting with MySQL databases led to its development. Over the years, MySQLi has evolved alongside MySQL versions, incorporating new features and performance improvements.
Uses: MySQLi is primarily used in web application development that requires interaction with MySQL databases. It is common in content management systems, e-commerce platforms, and custom applications that need to store and retrieve data efficiently.
Examples: A practical example of MySQLi is its use in a login system, where prepared statements are used to prevent SQL injection. Another example is in an inventory management application, where MySQLi is used to perform CRUD (Create, Read, Update, Delete) operations securely and efficiently.
