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
Write to a log file with PHP | Redips spideR Net
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：

然后去执行对应的代码：

页面是没有任何输出的：

否则会报错的：
Can't open /xxx/access_token/crifanLibTest.log file!
4.不过突然想起来：
之前已经学过了，
file_put_contents
就可以替代了：fopen，fwrite，fclose了。
所以再去优化为：
crifanLib.php

效果是：

-rw-r--r-- 1 root root 9524 Jul 27 18:16 crifanLib.php
-rwxrwxrwx 1 root root 561 Jul 27 18:18 wx_access_token.php

-rwxrwxrwx 1 root root 561 Jul 27 18:18 wx_access_token.php
root@chantyou:access_token# cat logTest.log
[2015-07-27 12:05:47] (wx_access_token) This is crifanLib log test message using file_put_contents
root@chantyou:access_token#
如图：
注：
期间参考：
PHP: is_resource – Manual
【总结】
1.此处可以通过：
fopen创建log文件
fwrite写入文件信息
fclose关闭文件
去实现log信息写入到文件中的。
2.更好的做法是：
直接用更方便的
file_put_contents直接输出内容到log文件
即可。
以上就是将log信息写入服务器中的log文件文件全部内容，希望大家喜欢。
