我有一个奇怪的问题，我的 nginx 服务器的错误日志不知何故搞砸了：PHP 错误似乎全部写在一行中并递归地重复。这样，llog 在一天之内就增长了几 GB！
这是一条线在错误日志中：
2020/03/26 16:58:45 [error] 29816#29816: *32 FastCGI sent in stderr: "PHP message: PHP Notice: Undefined variable: SCRIPT_FILENAME in /var/kunden/webs/my_web_app/www/pics/userpics/index.php on line 58PHP message: PHP Notice: Undefined variable: pfad in /var/kunden/webs/my_web_app/www/pics/userpics/index.php on line 60PHP message: PHP Notice: Undefined offset: 1 in /var/kunden/webs/my_web_app/www/pics/userpics/index.php on line 65PHP message: PHP Notice: Undefined variable: benutzer in /var/kunden/webs/my_web_app/www/pics/userpics/index.php on line 70PHP message: PHP Notice: Undefined index: PATH_TRANSLATED in /var/kunden/webs/my_web_app/www/pics/userpics/index.php on line 84PHP message: PHP Notice: Undefined variable: localdir in /var/kunden/webs/my_web_app/www/pics/userpics/index.php on line 96PHP message: PHP Notice: Undefined variable: localdir in /var/kunden/webs/my_web_app/www/pics/userpics/index.php on line 96PHP message: PHP Notice: Undefined variable: localdir in /var/kunden/webs/my_web_app/www/pics/userpics/index.php on line 96PHP message: PHP Notice: Undefined variable: localdir in /var/kunden/webs/my_web_app/www/pics/userpics/index.php on line 96PHP message: PHP Notice: Undefined variable: localdir in /var/kunden/webs/my_web_app/www/pics/userpics/index.php on line 96PHP message: PHP Notice: Undefined variable: localdir in /var/kunden/webs/my_web_app/www/pics/userpics/index.php on line 96PHP message: PHP Notice: Undefined variable: localdir in /var/kunden/webs/my_web_app/www/pics/userpics/index.php on line 96PHP message: PHP Notice: Undefined variable: localdir in /var/kunden/webs/my_web_app/www/pics/userpics/index.php on line 96PHP message: PHP Notice: Undefined variable: localdir in /var/kunden/webs/my_web_app/www/pics/userpics/index.php on line 96PHP message: PHP Notice: Undefined variable: localdir in /var/kunden/webs/my_web_app/www/pics/userpics/index.php on line 96PHP message: PHP Notice: Undefined variable: localdir in /var/kunden/webs/my_web_app/www/pics/userpics/index.php on li
行数在 2048 个字符后被截断。
在这里，我在每个新错误之前分割了几行：

这可能是从哪里来的？我如何在 nginx 中定义标准错误报告？
答案1
看起来 nginx 与 fastcgi 捆绑了发生在一页消息中一行消息中的所有错误。
如果脚本有如此多的错误（可能是由于 PHP 升级），则该行将被截断为 2048 个字符。
