# 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. Shutdown functions and object destructors will always be executed even if exit is called.

exit is a language construct and it can be called without parentheses if no `status` is passed.

### Parameters

`status`

  If `status` is a string, this function prints the `status` just before exiting.

  If `status` is an integer, that value will be used as the exit status and not printed. 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
?>`

Example #3 Shutdown functions and destructors run regardless

`<?php
class Foo
{
public function __destruct()
{
echo 'Destruct: ' . __METHOD__ . '()' . PHP_EOL;
}
}
function shutdown()
{
echo 'Shutdown: ' . __FUNCTION__ . '()' . PHP_EOL;
}
$foo = new Foo();
register_shutdown_function('shutdown');
exit();
echo 'This will not be output.';
?>`

The above example will output:

     Shutdown: shutdown()
     Destruct: Foo::__destruct()

### Notes

> Note: Because this is a language construct and not a function, it cannot be called using variable functions.

> Note:

> This language construct is equivalent to die().
