Describe the issue

The Memcached Metrics (in PHPMem v2.0.1) show thw following error:

Fatal error: Uncaught PDOException: could not find driver in 
/**/phpCacheAdmin-2.3.0/src/Dashboards/Memcached/MemcachedMetrics.php:38 Stack trace: #0
/**/phpCacheAdmin-2.3.0/src/Dashboards/Memcached/MemcachedMetrics.php(38): PDO->__construct() #1

{main} thrown in /**/phpCacheAdmin-2.3.0/src/Dashboards/Memcached/MemcachedMetrics.php on line 38

The Redis Metrics (in PHP Redis extension v6.2.0) shows the same issue in a more subtle way:

could not find driver

I looked at the PHP code, specifically:

phpCacheAdmin/src/Dashboards/Memcached/MemcachedMetrics.php

Line 38 in 6ba58d8

$this->pdo = new PDO('sqlite:'.$db);

After an apt install php8.3-sqlite3 on my system, the memcache and redis metrics worked as a charm!

Please add information in the documentation (maybe requirements) about this dependency and maybe improve the error message (include: sqlite driver) for those who don't read the documentation.

That's good idea.

I thought sqlite3 is installed on every system
