php - PSR2 - 键和值之间的多行数组缩进

Question

根据 PSR2，在多行数组的键和值之间留有空格的正确方法是什么。

$result = [
    'key1'           => 'value1',
    'another_key'    => 'value2',
    'some_other_key' => 'value3'
];

对比

$result = [
    'key1' => 'value1',
    'another_key' => 'value2',
    'some_other_key' => 'value3'
];

看起来第一个更具可读性，但我们有额外的空间。

根据:- PSR-2 multiline array indentation missing

PSR-2 doesn't define how arrays should be indented, or if they should even be indented at all, so PHPCS can't enforce any rules in this area.

When I have asked about arrays in other areas of the standard, the response was to treat them like a single object, and ignore them. So many PHPCS checks for PSR-2 actually skip right over arrays and don't do any checking inside them either.

So this isn't a bug, and it's also not something I can add to PHPCS because PSR-2 doesn't define an array formatting standard.

此线程中也陈述了同样的事情:- Question on proper Array syntax

There's no correct answer, beacuse the PSR is silent on the matter, but I think your assumption is reasonable. It's certainly my practice.

即使您检查此线程:- Coding Style Guide Additions

它只说明了关于添加 ， 没有关于添加空格的任何内容。

Arrays that span across multiple lines can have a trailing comma to make sure that adding new rows does not change the previous row, as well.
