PHP错误日志和换行符

Question

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
(
    [0] => 1
    [1] => 2
    [2] => 4
)
, 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!

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.
