我写了一个CGI script 来connect mysql database， 但出现了这样的error：

Global symbol "$host" requires explicit package name at login.cgi line 42.
Global symbol "$database" requires explicit package name at login.cgi line 43.
Global symbol "$user" requires explicit package name at login.cgi line 44.
Global symbol "$db" requires explicit package name at login.cgi line 47.
Global symbol "$host" requires explicit package name at login.cgi line 47.

Global symbol "%hash" requires explicit package name at login.cgi line 55.
Global symbol "$password_in_db" requires explicit package name at login.cgi line 58.

请问有人能告诉我是什么问题，非常谢谢你们的帮助！

你在declare variable时有没有加 "my"???
