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.

A:
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.
}

Good info, but keep in mind all the <code>class_exists</code> function is telling you is if there's ANY class in the defined include/require hierarchy named Memcache.

Would any other class name itself "memcache"? does any framework or library do this?

@Jeremy I've never seen anything else called memcache, so you're likely safe, especially all you have on the page is class_exists()

alternative would be checking the extension version? phpversion('memcache')
