Why is the \Memcached() class not found, although the php_memcache.dll library is included?

Question

PHP

Given:

• php7.4
  
• Symfony 5.x
  
• Windows 10
  
• phpstorm 2020.x
  
• PhpUnit 9.x
  

I'm trying to run tests locally, on my machine. At first, everything is fine, the test starts, gets to the point of execution, we try to go further. The test is functional, that is, it uses the framework fully, the only BUT is that it simulates a connection via HTTP (s). And at that moment the test fails with an error:

Error : Class 'Memcached' not found

Somewhere in the wilds of the container. Clear business, does not find the given class. But the problem is that the 'php_memcache.dll' library has been added to php.ini, the interpreter for which it is configured is correctly selected in the IDE, and viewing the output of phpinfo () gives this:

memcache.allow_failover
1
memcache.chunk_size
32768
memcache.compress_threshold
20000
memcache.default_port
11211
memcache.hash_function
crc32
memcache.hash_strategy
consistent
memcache.lock_timeout
15
memcache.max_failover_attempts
20
memcache.prefix_host_key
0
memcache.prefix_host_key_remove_subdomain
0
memcache.prefix_host_key_remove_www
1
memcache.prefix_static_key

memcache.protocol

memcache.redundancy

memcache.session_prefix_host_key

memcache.session_prefix_host_key_remove_subdomain
0
memcache.session_prefix_host_key_remove_www
1
memcache.session_prefix_static_key

memcache.session_redundancy
2
memcache.session_save_path

That is, everything seems to work as it should, but it does not work. Tell me what I could be missing? In what direction to dig?

Answer 1

memcache and memcache d are different things.
php_memcache.dll is not related to class \Memcache d
