Bug #71757 [NEW]: function () : void { return; } gives Fatal error
From: php dot net at sjappa dot nl
Operating system: Ubuntu 14.04 LTS
PHP version: 7.0.4
Package: Unknown/Other Function
Bug Type: Bug
Bug description:function () : void { return; } gives Fatal error
Description:
------------
According to the documentation on which can be found at
https://wiki.php.net/rfc/void_return_type,
the following should be
valid:
function returns_nothing(): void {
return; // valid
}
On our local development-server (PHP 7.1.0-dev (cli) (built: Nov 27 2015
16:10:23) ( NTS ) with Zend OPcache v7.0.6-dev, Copyright (c) 1999-2015,
by Zend Technologies) this works as described in the wiki.
We set up a new server in the data-center (PHP
7.0.4-3+deb.sury.org~trusty+4 (cli) ( NTS ) with Zend OPcache
v7.0.6-dev, Copyright (c) 1999-2016, by Zend Technologies), but when we
execute the same code there, it gives a PHP Fatal error: Uncaught
TypeError: Return value of test() must be an instance of void, null
returned in test.php:5\nStack trace:\n#0 test.php(8): test()\n#1
{main}\n thrown in test.php on line 5
Test script:
---------------
<?php
function test() : void
{
return;
}
test();
?>
Expected result:
----------------
Function should be valid, return; on a function() : void should be
correct and/or documentation should be updated to match the way PHP
reacts.
