我有一个PHP网站托管在运行于Windows Server 2012的IIS 8服务器上。我安装了PHP 5.3.28。我想在事件查看器中记录信息消息。我已经尝试了以下代码：

openlog('php', LOG_CONS | LOG_NDELAY | LOG_PID, LOG_USER | LOG_PERROR);
syslog(LOG_INFO, 'This is a message');
closelog();

字符串
我在php.ini中打开了error_reporting，并设置error_log=syslog
以下是事件查看器中的条目：

The description for Event ID 2 from source PHP-5.3.28 cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event: 

php[10052]
This is a message

型
我觉得php.ini中需要一些配置，但我无法确定它是什么，以便我可以为该日志消息提供通用描述。
