首先打开php的错误信息提示功能，在其已ubuntu为测试环境

vim /etc/php5/fpm/php.ini
打开错误提示

display_errors = On
因为用到的四fpm与nginx配合，所以还需要修改php-fpm.conf文件

vim /etc/php5/fpm/php-fpm.conf
再最后添加

tqyq

db.setProfilingLevel(1, 100);

In my case the df -h and du -sh mismatched by about 50% of the hard disk size.
This was caused by nginx keeping large log files in memory which had been deleted from disk.
The situation was then resolved by restarting nginx

echo $_GET['test'];
