CodeIgniter 3 - 配置 log_threshold

Question

好吧，我弄糊涂了。

在application/config.php 里面用 cmets 写着：

    | If you have enabled error logging, you can set an error threshold to
| determine what gets logged. Threshold options are:
| You can enable error logging by setting a threshold over zero. The
| threshold determines what gets logged. Threshold options are:
|
|   0 = Disables logging, Error logging TURNED OFF
|   1 = Error Messages (including PHP errors)
|   2 = Debug Messages
|   3 = Informational Messages
|   4 = All Messages
|
| You can also pass an array with threshold levels to show individual error types
|
|   array(2) = Debug Messages, without Error Messages

所以如果我想得到错误和调试消息而不是任何信息消息，我是否必须设置阈值

$config['log_threshold'] = 2;

或

$config['log_threshold'] = array(1, 2);

谁能给我一些澄清？

Answer 1

两者都可以，因为信息性消息的值为 3，而您想要的最大值为 2。

但是，如果您想记录信息和错误消息，但没有调试消息，则必须设置值 array(1, 3) 才能跳过调试消息。
