Note: This is not a real function, but a language construct.
Note: PHP >= 4.2.0 does NOT print the
status
if it is an integer.
The exit() function terminates execution of
the script. It prints status
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.
Note: This language construct is equivalent to die().
