页面是没有任何输出的：

然后的确生成了log文件了：

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


<"$timeStr ($scriptName) $logContent" . PHP_EOL, FILE_APPEND);
 }
}
 "htmlcode">

<"crifanLib.php";
//test log
$crifanLib = new crifanLib();
$crifanLib->logInit("/xxx/logTest.log");
$crifanLib->logWrite("This is crifanLib log test message using file_put_contents");
"mailto:root@chantyou:access_token">root@chantyou:access_token# ll

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。
