# exit

(PHP 3, PHP 4, PHP 5 )

exit -- Output a message and terminate the current script

## Description

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

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

> 참고: 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.

예 1. exit() example

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

예 2. exit() status example

`<?php //exit program normally exit; exit(); exit(0); //exit with an error code exit(1); exit(0376); //octal ?>`

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