PHP PSR-2 语句前/后新行

Question

示例 1:

$something = [1,2,3,4]
foreach ($something as $key => $value) {
    //code code code
}
$something2 = [];

我找不到关于 foreach 之前和之后的新直播的明确答案，PSR-2 对此有何评论？

Answer 1

Point 2.3 "Lines"可以选择在语句前后添加空行。在“段落”中分隔代码块以提高逻辑理解力和可读性仍然很有用。

Blank lines MAY be added to improve readability and to indicate related blocks of code.
