# exit

(PHP 3, PHP 4 )

exit -- Output a message and terminate the current script

## Description

void exit ( [string status])
void exit ( int status)

> Note: This is not a real function, but a language construct.

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 1 to 254, the exit status 255 is reserved by PHP and shall not be used.

> Note: The current CVS version does NOT print the `status` if it is an integer.

> Note: The die() function is an alias for exit().

Example 1. exit() example
    <?php

    $filename = '/path/to/data-file';
    $file = fopen ($filename, 'r')
        or exit("unable to open file ($filename)");

    ?>
