# exit

(PHP 4, PHP 5)

exit — Output a message and terminate the current script

### Description

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

Terminates execution of the script.

### Parameters

`status`

  If `status` is a string, this function prints the `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: PHP >= 4.2.0 does NOT print the `status` if it is an integer.

### Return Values

No value is returned.

### Examples

Example#1 exit() example

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

Example#2 exit() status example

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