Edit report at https://bugs.php.net/bug.php?id=79440&edit=1 ID: 79440 Comment by: daverandom@php.net Reported by: lmprogg at gmail dot com Summary: Object typehint sometimes seems to be misunderstood Status: Open Type: Bug Package: Class/Object related Operating System: Ubuntu PHP Version: 7.3.16 Block user comment: N Private report: N New Comment: Ha, no problem. I'm going to close this bug, if you need to re-report it then open a new one :-) Previous Comments: ------------------------------------------------------------------------ [2020-03-31 22:26:01] daverandom@php.net Just for the sake of sanity, can you double-triple-super check that PHPUnit is executing under the PHP version you think it is? A simple var_dump(\PHP_VERSION); in the offending test will suffice. Also, can you sanity check that there is no use statement which affects the name "object" in the file? Just in the interests of eliminating PEBCAK before going any further :-) ------------------------------------------------------------------------ [2020-03-31 22:24:28] lmprogg at gmail dot com I am sorry, seems that the tests are run with a different version. Could have saved the effort creating this. Late hour. If I double checked that is indeed not only outputting 7.3.16 for the version but actually using it, I'll report back ... :/ ------------------------------------------------------------------------ [2020-03-31 22:18:50] lmprogg at gmail dot com Description: ------------ It is difficult for me to make this reproducible. Short notice on the setup: A local vm with vagrant and php 7.3.16: PHP 7.3.16-1+ubuntu16.04.1+deb.sury.org+1 (cli) (built: Mar 20 2020 13:51:21) ( NTS ) Copyright (c) 1997-2018 The PHP Group Zend Engine v3.3.16, Copyright (c) 1998-2018 Zend Technologies with Zend OPcache v7.3.16-1+ubuntu16.04.1+deb.sury.org+1, Copyright (c) 1999-2018, by Zend Technologies That one does *not* have the problem. Then there is an aws instance that is running the following version: PHP 7.3.16-1+ubuntu18.04.1+deb.sury.org+1 (cli) (built: Mar 20 2020 13:51:46) ( NTS ) Copyright (c) 1997-2018 The PHP Group Zend Engine v3.3.16, Copyright (c) 1998-2018 Zend Technologies with Zend OPcache v7.3.16-1+ubuntu18.04.1+deb.sury.org+1, Copyright (c) 1999-2018, by Zend Technologies This one *has* the problem. The following happens (I also included a little code snippet, although it may be hard to reproduce). Whenever a typehint "object" is encountered (in my failing case, it is PHPUnit, but it happens on any typehint "object", even in other functions): [TypeError] Argument 5 passed to PHPUnit\Framework\MockObject\Invocation::__construct() must be an instance of PHPUnit\Framework\MockObject\object, instance of Mock_MyClient_070b46a8 given, called in /project/vendor/phpunit/phpunit/src/Framework/MockObject/MockClass.php(42) : eval()'d code on line 47 This is the line that does not pass the typecheck: (PHPUnit 9.0.2) public function __construct(string $className, string $methodName, array $parameters, string $returnType, object $object, bool $cloneObjects = false, bool $proxiedCall = false) The 5th parameter seems to be misunderstood to be an "object" of the same namespace, instead of the reserved "object" keyword. (which should be passed by the mock passed in) I first had this in 7.3.9, and then upgraded to the latest 7.3.16, but the problem still persisted on the AWS instance. I am not sure if this is a bug or just a configuration issue, but it seems that some versions (I am not sure how they differ) are unable to understand this relatively new typehint which was introduced in php 7.2. I included a little snippet that *might* reproduce it. If you need more info, please tell me, it is just a little hard to get it from the aws instance (which is why I did not go haywire and collected everything beforehand). The code in the snippet should actually just produce a failure because of different contents that are compared, but throws this on the aws instance: [TypeError] Argument 1 passed to Test\Namespace1\MyTest::getMyResult() must be an instance of Test\Namespace1\object, instance of stdClass given, called in /project/tests/Test/Namespace1/MyTest.php on line 14 (The line number might differ) I hope someone might have an idea how this can fit together and guide me in the right direction. Happy to assist with further input. Good night!
