如何访问代码中使用的任何 foreach 的 $loop？

Answer 1

您可以使用$loop->parent访问当前循环的父循环。

Answer 2

在我的例子中 (Laravel 6.8) $loop->parent 看起来像这样

[
{"iteration":1,"index":0,"remaining":1,"count":2,"first":true,"last":false,"odd":true,"even":false,"depth":1,"parent":null},
{"iteration":2,"index":1,"remaining":0,"count":2,"first":false,"last":true,"odd":false,"even":true,"depth":1,"parent":null}
]
