将log信息写入服务器中的log文件文件，折腾了一大圈终于找到了解决方案，具体内容如下：

折腾：

【记录】php中如何写类和如何使用类

期间，需要整理出一份，可配置的，通用的，log系统。

支持写入log信息到log文件中。

【折腾过程】

1.搜：

php log to file

参考：

PHP: error_log – Manual

PHP: syslog – Manual

How to create logs with PHP – Web Services Wiki

下载代码：

Download redips10.tar.gz

2.期间：

【已解决】PHP中函数前面加上at符号@的作用

3.然后用代码：

crifanLib.php

然后去执行对应的代码：

页面是没有任何输出的：

然后的确生成了log文件了：

就可以替代了：fopen，fwrite，fclose了。

所以再去优化为：
