未找到 PHP 5.4 和 Laravel 类Memcached

我知道这些问题大概有10个，但没有一个完全适合我.

Steps completed:

1. Installed memcache
2. installed php memcache module
3. 已更新laravel配置以使用memcache
4. 重启服务器

php info results:

memcache.allow_failover 1   1
memcache.chunk_size 8192    8192
memcache.default_port   11211   11211

memcache.hash_function  crc32   crc32
memcache.hash_strategy  standard    standard
memcache.max_failover_attempts  20  20

它在php-m中称为"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

我已经通过多种方法确认了memcache的安装.已确认安装了php模块.仍然不允许我使用memcached类.
