PHP_EOL, FILE_APPEND); } } ?>
测试文件为：
<?php /* Author: Crifan Li Version: 2015-07-27 Contact: Function: test crifanLib log */ include_once "crifanLib.php"; //test log $crifanLib = new crifanLib(); $crifanLib->logInit("/xxx/logTest.log"); $crifanLib->logWrite("This is crifanLib log test message using file_put_contents"); ?>
效果是：
root@chantyou:access_token# ll
total 16
-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
root@chantyou:access_token# ll

-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。
