Does exit; terminate php parsing on current php document or at all?

Question

When including a file in another, I want to end the parsing after a certain if statement. Is it ill advised to use this method for terminating a parsing of a script, and does exit; terminate parsing at all, or just the rest of the current php file?

Answer 1

Exit terminates php execution.

Answer 2

die() is equivalent to exit() so it will terminate the script

Answer 3

exit stops the whole script. In included files you can use return to exit from the current file without stopping the whole script.
