Undocumented Complex Regex Pattern 
Tell me more
What is the issue?
The regex pattern '/[^A-Za-z0-9_\-]/' lacks clarity and documentation about its purpose.
Why this matters
Complex regex patterns without explanation make code maintenance difficult and increase cognitive load for developers trying to understand the key sanitization logic.
Suggested change ∙ Feature Preview
// Define regex pattern with explanation
protected function fixKey(string $key): string
{
$key = $this->getKeyFromContainer($key);
// Replace any character that is not alphanumeric, underscore, or hyphen with a hyphen
$key = preg_replace('/[^A-Za-z0-9_\-]/', '-', $key);
return "cache-" . $key;

Description by Korbit AI
What change is being made?
Standardize the keys used in
MemcachedEngine.phpby replacing non-alphanumeric characters with hyphens in thefixKeymethod.Why are these changes being made?
To ensure consistency and compatibility of Memcached keys by sanitizing them, preventing issues with unsupported characters that can cause unexpected errors during caching operations. This approach minimizes potential key conflicts and maintains uniformity within the cache storage system.
