exit -- Output a message and terminate the current script
Opis
void exit ( [string status] ) void exit ( int status )
Terminates execution of the script.
Parametry
status
If status is a string, this function prints the
status, if set as a string just before exiting.
If status is an integer, that
value will also be used as the exit status. Exit statuses should be in
the range 0 to 254, the exit status 255 is reserved by PHP and shall
not be used. The status 0 is used to terminate the program
successfully.
Notatka:
PHP >= 4.2.0 does NOT print the status
if it is an integer.
