exit()The function outputs a message and exits the current script. This function is an alias of thedie()function.

Syntax:

exit ( string $status )

exit ( int $status )

• If $status is a string, the function will print $status before exiting .

• If $status is an int, the value will be used as the exit status code and will not be printed. Exit status codes should be in the range 0 to 254, and the exit status code 255, which is reserved by PHP, should not be used. Status code 0 is used to terminate the program successfully.
