PHP memcached Fatal error: Class 'Memcache' not found

I've pasted the example from php.net for using memcached in php and I'm getting:

Fatal error: Class 'Memcache' not found

I have this in my php.ini:

[memcache]
memcache.hash_strategy = "consistent"
memcache.max_failover_attemps = 100
memcache.allow_failover = 1

Here's info from php -i and php -m respectively:

php -i | grep -i memcache
memcached
memcached support => enabled
libmemcached version => 0.37
Registered save handlers => files user sqlite memcached

php -m | grep -i memcache
memcached

So php seems to have loaded memcached as a module, and php info says that it is loaded and is using v .37. I have not tried yet via apache, I've only been using this through cli right now. Any thoughts?

Solution

  • There are two extensions for memcached in PHP, "memcache" and "memcached".

    It looks like you're trying to use one ("memcache"), but the other is installed ("memcached").

    In the ~13 years since this answer was written, much has changed in the PHP community. The old memcache extension seems to be unmaintained, so please use the memcached extension instead if you can. It's a better option regardless!
