How to install memcache extension for PHP 7 on CentOS 7?

Question

linux

I had to move from PHP 5.6 (CentOS 6) to PHP 7.1 (CentOS 7). I installed PHP 7.1 and other extensions from the IUS repository, but I don’t understand what to do with memcache. Additionally, the issue of switching from memcache to memcache d has surfaced .
Here, for example, they write that there is no stable version of the extension: https://github.com/iuscommunity/wishlist/issues/111
The memcache d extension is at least supported by developers, but memcache has not been updated for several years.
https://pecl.php.net/package/memcache
Where do you get the version for 7.1 then? Or does it not need to be rewritten to adapt the extension? How does it all work? And which extension is currently more popular? Maybe everyone switched to memcache d a long time ago, and I just live in the last century?
What will the "pecl install memcache" command do? First, it tries to install the old version 2.2.7. Second, will it work with PHP 7.1? I installed PEAR from the same IUS, but which version of PHP is it tied to? Or is the version determined automatically? When I entered the command, I got an error:

The php-devel package is required for use of this command.
ERROR: `phpize' failed

I assume that it would be fixed by installing php71u-devel, but would it all work?
I'm trying to figure it all out, but the more I read, the more mess in my head. Please explain how it all works and what to do with it all.

Why not use the REMI repo? And pull all PHP with modules from there.
Here is php7.1 in a CentOS7 based container:
