Alright, the problem solve. So I just need to mark wampserver32 to use 5.6 instead of 7.x. Thanks.

But I have an issue to switch from wamp64 to wamp32. I can't connect the wamp32 mysql, it said wrong password.

Switching from 64 to 32 is big cost for me. I still prefer the complete solution: adk 64 bit for php

I did the same thing as you except the 2. What MSVCR does in this issue?

Attachment is my wampserver info.

1. I installed the latest version of wampserver 32-bit.

2. To start the servers it was necessary to install MSVCR 110 and 120.

3. Switched the PHP version to 5.6

4. Then I copied extensions to C:\wamp\bin\php\php5.6.38\ext

5. Added them to the Dynamic Extensions section of the PHP configuration - php.ini in the wampserver menu, turns out it is phpForApache.ini in C:\wamp\bin\php\php5.6.38 folder.

extension=php56_pdo_valentina
extension=php56_valentina

6. Restarted all services from wampserver menu.

Now the phpinfo() shows that the extensions are loaded.

What version of wampserver do you use? My php.ini file looks very different from yours (other extensions, ".dll" added to extension name)

I'll try to install myself.

Even I install wampserver 32bit, still cant load the extension. Please check the attachment, I add these two lines in php.ini, and also copy two valentina dlls to wamp32 php ext folder.

Anything wrong?

Now you can use 32-bit wampserver with VPHP. Or it is undesirable to install it?

So what is the solution now? Do I need to download 64bit php adk? But it seems there is no for download

Hello Gary,

I think the problem is in the architecture mismatch.
Currently, VPHP extensions are 32-bit, so they can be used with 32-bit PHP.
