The extension for php is grpc. It is aboslute hell. Firstly it would not discover the extension and now I have had to reinstall php like 5 times as well as a new install of WAMP. Now it discovers the file, it gives me "The specified procedure could not be found". I am running on PHP 7.3.12 64 bit on a thread safe system. I have downloaded both the latest version of grpc from pecl as well as an older one I thought would work. Rather, when I test the command prompt of the file (wampdir/php/php7.3.12/> php.exe --ini) it simply crashes with this error.
and then will print out in the terminal about not being able to find the procedure point. I have the correct system version but it simply will not work.
Wow... To anyone in the future with this issue, reinstall wamp to the newest version. Checkout this kid's tutorial https://www.youtube.com/watch?v=1xK7q6aL_-4
Make SURE you have changed the php.ini files in wamp/bin/php/php.7.x.y/php.ini and wamp/bin/php/php.7.x.y/phpForApache.ini
If need be give the abosulte path.
I did this but I was using 7.3.10 but attempted the newest plugin version for my system type on 7.4.2. Dragged the right extension in. Changed the ini's to extension=grpc. I did not need to change extension_dir. Started wamp, changed php version and the errors went. Don't know how.
