False Positive: Squiz.Arrays.ArrayDeclaration.ValueNoNewline: The first value in a multi-value array must be on a new line

[bendavies]

vendor/bin/phpcs --version
PHP_CodeSniffer version 3.5.5 (stable) by Squiz (http://www.squiz.net)

Given

<?php

declare(strict_types=1);

function foo(): Generator
{
    yield 'foo' => [
        static function (): array {
            return [];
        },
    ];
}

vendor/bin/phpcs test.php --standard=Squiz --sniffs=Squiz.Arrays.ArrayDeclaration -s

FILE: test.php
-----------------------------------------------------------------------------------------------------------------------------
FOUND 1 ERROR AFFECTING 1 LINE
-----------------------------------------------------------------------------------------------------------------------------
 8 | ERROR | [x] The first value in a multi-value array must be on a new line
   |       |     (Squiz.Arrays.ArrayDeclaration.ValueNoNewline)

if static is removed from the function, there is no violation.

Same bug here with similar code:

		$server = new Server([
			static function (ServerRequestInterface $request, callable $next) {
				return $next($request);
			},
		]);

Also nested arrays are affected by this, I don't know if you want this in a separate issue?

<?php

// 1)
$foo = [[1,
  2,
  3,
]];

// 2)
$foo = [[
  1,
  2,
  3,
]];

// 3)
$foo = [[1 => 1,
  2 => 2,
  3 => 3,
]];

// 4)
$foo = [[
  1 => 1,
  2 => 2,
  3 => 3,
]];

// 5)
$foo = [lorem(
  1,
  2,
  3
)];

Cases 1) and 3) report errors as before 3.5.5, cases 2) and 4) were ok before (and I consider them corrected versions of 1) and 3), but now are throwing errors.

I think this is consistent with 5) which was ok both before and now.

  4 | ERROR | [x] The first value in a multi-value array must be on a new line (Squiz.Arrays.ArrayDeclaration.ValueNoNewline)
  4 | ERROR | [x] The first value in a multi-value array must be on a new line (Squiz.Arrays.ArrayDeclaration.ValueNoNewline)
 10 | ERROR | [x] The first value in a multi-value array must be on a new line (Squiz.Arrays.ArrayDeclaration.ValueNoNewline)
 17 | ERROR | [x] The first value in a multi-value array must be on a new line (Squiz.Arrays.ArrayDeclaration.ValueNoNewline)
 17 | ERROR | [x] The first index in a multi-value array must be on a new line (Squiz.Arrays.ArrayDeclaration.IndexNoNewline)
 23 | ERROR | [x] The first value in a multi-value array must be on a new line (Squiz.Arrays.ArrayDeclaration.ValueNoNewline)

So this affects also Squiz.Arrays.ArrayDeclaration.IndexNoNewline (not only ValueNoNewline).

                [
                    12345,
                    [0],
                    (object) [
                        'type' => 'int',
                    ],
                ],

This is also a false positive, object is in the right place

Related #582.

[fezfez]

same with

        yield 'testActiveOnly' => [
            static function () {
                return ['inactive' => '2'];
            },
        ];

This should be related to #3059 and #3060 (not a Slevomat issue per se).

Hi, I'm using phpcs version 3.5.8 and still have this problem.
Code:

public function getUserInput(): array
{
    return [];
}

Result:

FOUND 2 ERRORS AFFECTING 1 LINE
-------------------------------------------------------------------------------
 97 | ERROR | [x] The first value in a multi-value array must be on a new line
 97 | ERROR | [x] Each value in a multi-line array must be on a new line
-------------------------------------------------------------------------------
PHPCBF CAN FIX THE 2 MARKED SNIFF VIOLATIONS AUTOMATICALLY

But, if I try to use PHPCBF:

-----------------------------------------------------------------------
FILE                                                   FIXED  REMAINING

-----------------------------------------------------------------------
A TOTAL OF -3 ERRORS WERE FIXED IN 1 FILE

2 errors became -3... 🤔
