Unpacking associative arrays in PHP 8.1 produces Squiz.Arrays.ArrayDeclaration.NoKeySpecified respectively Squiz.Arrays.ArrayDeclaration.KeySpecified #3557
Description
Describe the bug
Since PHP 8.1 unpacking of associative arrays is supported.
Unpacking an associative array into another results in one of the errors Squiz.Arrays.ArrayDeclaration.NoKeySpecified or Squiz.Arrays.ArrayDeclaration.KeySpecified (depending on the position).
Code sample
<?php
$arr = [
'a' => 1,
'b' => 2,
];
$merged1 = [
'c' => 3,
...$arr,
];
$merged2 = [
...$arr,
'c' => 3,
];Custom ruleset
<?xml version="1.0" encoding="UTF-8"?>
<ruleset>
<rule ref="Squiz.Arrays.ArrayDeclaration"/>
</ruleset>To reproduce
-------------------------------------------------------------------------------------------------------------------------
FOUND 2 ERRORS AFFECTING 2 LINES
-------------------------------------------------------------------------------------------------------------------------
10 | ERROR | No key specified for array entry; first entry specifies key
| | (Squiz.Arrays.ArrayDeclaration.NoKeySpecified)
15 | ERROR | Key specified for array entry; first entry has no key (Squiz.Arrays.ArrayDeclaration.KeySpecified)
-------------------------------------------------------------------------------------------------------------------------
Expected behavior
This should not result in an error:
- ideally PHP_CodeSniffer can check if the unpacked array is associative
- if thats not possible, array unpacking should be ignored by this rule
