XAMPP和Interbase:在Windows 10上调用未定义的函数base_connect()

While coding a web aplication using php 7 on xampp using Interbase as database I keep getting the fallowing error message:

Call to undefined function xxx\ibase_connect()

When trying to check if the interbase extension is loaded with extension_loaded("interbase"); it returns false.

I already edited php.ini to enable php to work with Interbase changing this line: ;extension=interbase to extension=interbase and even extension=interbase.dll.

I copied gds32.dll to System32 and to SysWOW64.

The worse thing is that yesterday it was working!
