PSR-2 是否需要垂直对齐？

Question

这两者之间允许什么：

$value = 'value';
$user = 'John';
$timestamp = 1480927909;
$day = date('Y-m-d', $timestamp);

或

$value     = 'value';
$user      = 'John';
$timestamp = 1480927909;
$day       = date('Y-m-d', $timestamp);

Answer 1

PSR-2对这种行间对齐没有具体规定：

来自PSR-2 Conclusion：

There are many elements of style and practice intentionally omitted by this guide. These include but are not limited to:

Declaration of global variables and global constants

Declaration of functions

Operators and assignment

Inter-line alignment

Comments and documentation blocks

Class name prefixes and suffixes

Best practices

Future recommendations MAY revise and extend this guide to address those or other elements of style and practice.

值得一提的是，PHP-FIG 组 discussed for PSR-1 行间对齐，但已从最终版本中删除：

The way-back original long-form PSR-1 covered inter-line alignment, globals, ternaries, assignment, and lots of other things. Those ended up getting removed for various reasons; their epitaph is at the conclusion of PSR-2.
