Frequently Asked Questions (FAQs):

1. What is the difference between GET and POST methods in PHP form handling?
   • Answer: GET displays data in the URL, ideal for non-sensitive information and bookmarking pages. POST does not display data in the URL, used for transmitting sensitive data.
2. How do PDO and MySQLi differ in PHP?
   • Answer: PDO supports multiple databases, offers named parameters, and has better error handling. MySQLi is specific to MySQL databases and is faster for executing simple queries.
3. Can PHP arrays store multiple data types?
   • Answer: Yes, PHP arrays are heterogeneous, meaning they can store mixed data types (integers, strings, objects, etc.).
4. What is PHP OOP and how does it benefit coding?
   • Answer: PHP OOP (Object-Oriented Programming) introduces concepts like classes and objects, making code more modular, reusable, and easier to maintain.
5. How do PHP sessions work?
   • Answer: PHP sessions store user information on the server for later use, allowing data persistence across multiple pages.
6. What are PHP Superglobals and give an example?
   • Answer: Superglobals are built-in variables that are always accessible, regardless of scope. Example: $_POST, $_GET, $_SESSION.
7. How does PHP handle error reporting?
   • Answer: PHP uses functions like error_reporting() and set_error_handler() to manage how errors are reported and handled.
8. What are prepared statements in PHP?
   • Answer: Prepared statements separate SQL commands from data, enhancing security by preventing SQL injection attacks.
9. Explain inheritance in PHP OOP.
   • Answer: Inheritance allows a class to inherit properties and methods from another class, promoting code reusability.
10. What are best practices for PHP security?
    • Answer: Practices include using prepared statements for database queries, validating and sanitizing user input, and implementing proper error handling.
