Constants are commonly used to store configuration values such as site settings, database credentials, and fixed numbers that should remain unchanged. In PHP, constants can be created using the define() function or the const keyword. Using constants correctly helps make code more readable, secure, and easier to maintain. This quiz focuses on how constants are declared, accessed, and used in PHP programs. Read the instructions carefully before you begin.
