How do I test if memcache or memcached (for PHP) is installed on my Apache webserver?

Memcache is a caching daemon designed especially for dynamic web applications to decrease database load by storing objects in memory.

Answer

You can look at phpinfo() or check if any of the functions of memcache is available. Ultimately, check whether the Memcache class exists or not.

e.g.

if(class_exists('Memcache')){
  // Memcache is enabled.
}
