Welcome to the PHP Magic Constants Quiz.

This quiz tests your understanding of magic constants in PHP, which are predefined constants that change depending on where they are used in a script. Magic constants provide useful information about the current file, directory, line number, function, class, and method. They are commonly used for debugging, logging, and understanding code structure. Unlike regular constants, magic constants are automatically updated by PHP based on the context. A strong understanding of magic constants helps you write more informative and maintainable PHP code. Read the instructions carefully before you begin.
