It is in php -m as "memcache"

However, when i go into php artisan tinker and try to do any caching I get the typical Fatal error: Class 'Memcached' not found in vendor/laravel/framework/src/Illuminate/Cache/MemcachedConnector.php on line 44

TL;DR;

I have confirmed install of memcache through multiple methods. Confirmed the module for php is installed. Still not allowing me to use memcached class.

Answer 1

Memcache and Memcached are two different PHP extensions. Memcache is the older deprecated one. Memcached is a much newer and fully supported extension.

Check out http://pecl.php.net/package/memcached

You may need to also install libmemcached https://launchpad.net/libmemcached/+download

Answer 2

If you are in a ubuntu environment, try to install Memcached with this:

sudo apt-get install php5-memcached

After that restart your server with

sudo service lighttpd restart

or

sudo service apachectl2 restart

or

sudo service nginx restart

Answer 3

apt-get install php-memcached

Solved the issue for "Class MemCached not found" coming from Laravel.

Answer 4

In Laravel/Lumen 5.4 just replace the CACHE_DRIVER=file in .env file, the artisan command will work perfectly, But you will not get all the command as same as laravel.
