With PHP 8.0 (beta4) instantiating a new instance with a FQN (i.e. including the namespace), PHPCS will raise the following unrelated issue:

Parentheses must be used when instantiating a new class

Code sample

<?php namespace ArthurHoaro; class PhpCsBugReport { public function method(): void { $foo = new \DateTime(); $foo = new \Other\Namespance\Unknown(); $foo = new Unknown(); } }

Custom ruleset
N/A

To reproduce
Steps to reproduce the behavior:

1. Create a file called PhpCsBugReport.php with the code sample above.
2. Run composer require "squizlabs/php_codesniffer"
3. Using PHP 8.0 run vendor/bin/phpcs --standard=PSR12 PhpCsBugReport.php.
4. See error message displayed

FILE: /usr/src/myapp/PhpCsBugReport.php ---------------------------------------------------------------------- FOUND 2 ERRORS AFFECTING 2 LINES ---------------------------------------------------------------------- 9 | ERROR | [x] Parentheses must be used when instantiating a new | | class 10 | ERROR | [x] Parentheses must be used when instantiating a new | | class ---------------------------------------------------------------------- PHPCBF CAN FIX THE 2 MARKED SNIFF VIOLATIONS AUTOMATICALLY ---------------------------------------------------------------------- 

Expected behavior
Same behavior as with PHP 7.x, no issue should be raised here.

Versions (please complete the following information):

• OS: Ubuntu 20.04
• PHP: 8.0.0-beta4
• PHPCS: 3.5.6
• Standard: PSR12

Additional information

Running PHPCBF will generate a PHP syntax error:

<?php namespace ArthurHoaro; class PhpCsBugReport { public function method(): void { $foo = new() \DateTime(); $foo = new() \Other\Namespance\Unknown(); $foo = new Unknown(); } }
