PHP错误日志和换行符 [英] PHP error log and newline chars

问题描述

在两个不同的安装（运行MAMP / OSX的开发笔记本电脑和一个dev服务器运行debian）我在调试时看到错误日志中的不同结果。

  error_log（print_r 4），1））; 
  

在Debian上，这出现在/var/log/apache2/error.log中，作为

  [Thu Jul 30 11:32:34 2009] [error] [client 118.93.246.104] Array\\\
（\\\
 [0] => 1\\\
 [1] => 2\\\
 [2] => 4\\\
）\\\
，refferer：http://dev.example.org/ 
  

在OSX上，这出现在/ Applications / MAMP / logs / php_error_log中，作为

  [2009年7月30日11:34:00]数组
（
 [0] => 1 
 [1] => 2 
 [2] => 4 
）
  

我更喜欢MAMP调试方式（将日志文件重定位到/ Applications目录除外）。

谢谢！

解决方案

Chris，你应该能够改变在Debian的php.ini中的error_log指令指向一个文件。如果这是未定义的，它将通过不支持多行的syslog。

error_log 指令

What's the PHP config setting which allows or prevents newlines in debug output from being escaped?

On two different installs (a dev laptop running MAMP/OSX, and a dev server running debian) I see different results in the error logs when debugging.

error_log(print_r(array(1,2,4),1));

On Debian this appears in /var/log/apache2/error.log as

[Thu Jul 30 11:32:34 2009] [error] [client 118.93.246.104] Array\n(\n    [0] => 1\n    [1] => 2\n    [2] => 4\n)\n, referer: http://dev.example.org/

On OSX this appears in /Applications/MAMP/logs/php_error_log as

[30-Jul-2009 11:34:00] Array
(
    [0] => 1
    [1] => 2
    [2] => 4
)

I prefer the MAMP way for debugging (apart from relocating logfiles to the /Applications directory).

Thanks!

解决方案

Chris, you should be able to change the error_log directive in your php.ini on Debian to point to a file. If this is undefined, it will go through syslog which doesn't support multiple lines.

Details:

error_log function

error_log directive
