Hello, i install memcached by this tutorial with debian 11 https://www.howtoforge.com/how-to-install-and-configure-memcached-on-debian-11/ but does not work for me. I install all what i need, memcached is running fine, but in my site with php 5.6 and 7.4 a can not see as enabled in phpinfo, there is no memcached. Where is the problem? Or this is only for php 8? I dont test it, just php 7.4 as latest php for me.
You have to install the memcached extensions of these additional PHP versions: apt install php5.6-memcached php7.4-memcached and restart the php-fpm services of these PHP versions
