How to fix "PHP Startup: Unable to load dynamic library" error?

Question

PHP

The project requires version "php": "^7.1.3", I had 7.0.14 installed in modules in version 5.2.2.0 I had to download OS version 5.2.8 In modules, php 7.2 * 64 Apache 7.2 * 62
was selected In phpinfo also infa that version 7.2
The path and version of php were changed in the parameters: Computer -> System property -> Advanced parameters -> "Advanced: Environment Variable" In the system variables "Path" D:\OpenServer\modules\php\PHP- 7.2*64
But in cmd, when you run the "composer update" command, now it swears at the lack of a bunch of libraries

The problem was that there were crooked paths in the php.ini file.
It all started with the W drive, and I don’t have it at all. I changed all w:\ and w:/ (you need to see which drive you have) to the correct path. everything worked 100% (you need to restart the console).
I understand that the author does not need my comment anymore, but suddenly someone will see this and it will help someone.
