php – PSR-2是否需要垂直对齐？

导读：这两者之间允许什么： $value = 'value';$user = 'John';$timestamp = 1480927909;$day = date('Y-m-d',$timestamp); 要么 $value = 'value';$user = 'John';$timestamp = 1480927909;$day = date('Y-m-d',$timestamp); PSR-2没有针对这种线间对齐的具体规则

这两者之间允许什么：

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

要么

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

PSR-2没有针对这种线间对齐的具体规则：

从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.

对于它的价值,PHP-FIG Group的行间对齐是discussed for PSR-1,但是从最终版本中删除了：

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.
