雄辩地保持10条最新行

Question

我有雄辩的日志处理程序，我想仅通过删除其他行来将其限制在最新的10行中。

如果我在行数少于10时尝试$model->orderBy('id', 'desc')->skip(10)->delete();，则会删除所有行。

Answer 1

这是解决方案，但不是很优雅。

$ar1 = ["Dublin", "Budapest", "Copenhagen"];
$ar2 = ["Ireland", "Hungary", "Denmark"];
$ANSWER = $ar2[0] . " = " . $ar1[0] . ", " . $ar2[1] . " = " . $ar1[1]. ", " . $ar2[2] . " = " . $ar1[2];
