PHP erroru log to syslog to a custom file pipe来跟踪错误。

Posted 2021-02-25

So i wanted to spit all my error_log(); and error_reporting(E_ALL); to syslog on my MacOSX and syslog would output it on a custom file.

use this line so all your errors are logged.
<?php
error_reporting(E_ALL);
?>
 
go to your php.ini and set the following:
error_log = syslog
 
go to your apache.conf (httpd.conf) and set the following:
ErrorLog syslog:local3
 
go to your syslog.conf and set the following at the very end of the file:
local3.*   /var/log/httpd-php.log
 
then look for a line like this: 
*.notice;authpriv,remoteauth,ftp,install,internal.none      /var/log/system.log
 
and add local3.none
*.notice;authpriv,remoteauth,ftp,install,internal.none      /var/log/system.log
 
this will make sure httpd php errors won't log to your /var/log/system.log file that's reserved for your machine logs.
 
and you are set
 
when you want to log something, use error_log(); example:
error_log("Error: " .$user. " is not authenticated");
 
and then to view your errors in real time:
tail -F /var/log/httpd-php.log 
 
you can also color this using "colorize" on OSX/FreeBSD or "ccze" on Linux.
 
enjoy!
