The die() and exit() functions do the exact same thing?

The die() and exit() functions in PHP serve the same purpose: they terminate the script execution. However, die() is essentially an alias for exit(), allowing for a more expressive way to indicate that the script has ended due to an error or a specific condition. Both can take an optional message as an argument to output before terminating. Therefore, while they are functionally identical, die() is often used for clarity in error handling contexts.
