【问题】
折腾：
【已解决】将Log函数的参数改变为类似于sprintf的动态个数的可变参数
期间，已经调试了半天了，
对于如下代码：

去运行wx_access_token.php，但是没有任何输出：
【折腾过程】
1.看来只是单独添加调试代码，echo，print，则是效果不好。
2.想办法，去看服务器上面的PHP是否正常运行，web服务器是否正常，以及PHP的相关log。

看起来是：
web服务器是正常的
PHP也是正常的。
3.再去看PHP的log：
【基本解决】CentOS 7中查看PHP运行时的Log文件日志信息
4.然后继续去试试运行PHP代码，看看是否log中有错误日志输出。
结果还是没有任何log输出。
5.然后直接去用：
1 | echo "In" . __FILE__; |
是可以输出结果的：
1 | In/var/www/....../public_html/php/access_token/wx_access_token.php |
6.再用：
1 2 3 | echo "In" . __FILE__;include_once "crifanLib.php";echo "include OK"; |
结果就出错，后面的echo不显示了。
把：
1 | function logWrite($logFormat, $logArgs = ()) { |
变成：
1 | function logWrite($logFormat) { |
试试：
结果真的就
include OK
了。
7.所以，此处还是要去研究那个：
然后就解决了此处的问题了。
【总结】
此处是由于，PHP中初始化数组为空，写成了
1 | $logArgs = () |
导致语法出错，然后结果PHP代码运行没有任何输出。
改为
1 | $logArgs = [] |
或：
1 | $logArgs = array() |
都可以。
