php - Does the debug.log do log rotation?

文章数量:1122832

This is more like of an inquiry.
So I enabled my WP_DEBUG_LOG to true.
It does work though, debug.log is in my wp-content's directory.
But does it also do log rotation like different file for each day?

Example:

Today's file - debug.log
Yesterday's - 2019-12-18-101010-debug.log

Does it work like this? Or just debug.log all through out?

No, it creates only one file. There is no log rotation involved.

But... Sometimes “but” can be a good thing ;)

WP uses error_log for its debug log, so you can change its location using:

ini_set( 'error_log', WP_CONTENT_DIR . '/debug-' . date('Y-m-d') . '.log' );

An other way is set it in wp-config.php:

define( 'WP_DEBUG_LOG', (defined( 'WP_CONTENT_DIR' ) ? WP_CONTENT_DIR : __DIR__ . '/wp-content') . '/debug-' . date('Y-m-d') . '.log' );
