After searching for information, I found that my original server environment was version 5.2, and after replacing the server, I upgraded to version 5.4, so there was a parameter transfer error.

Fatal error:Call-time pass-by-reference has been removed

When PHP upgrades to 5.5, the following error message appears during program execution

When calling

GetFormMethod ($method)
