exit

(PHP 4, PHP 5, PHP 7)

exitOutput a message and terminate the current script

Description

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

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.

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().
