Requires the memcache PECL extension to work, uses persistent connections.
Configuration options:
- string host The host to connect to, defaults to localhost.
- int port The port to connect to, defaults to the default port 11211.
Important notes:
- This script does not synchronize multiple read/write accesses to the cache in the
sense of a transaction.
- This subclass will override the automatic serialization setting you made, as the
memcache extension does this automatically.
- Since this is about performance, (and memcached doesn't allow it in any other way),
the get and exist calls are merged. Get will return false in case that the required
key was not found. This effectively means that you cannot store "false" as a value.
- The class will automatically add the name of the cache instance to the cache keys.
Methods
__construct ()
We use persistant connections, so we let midcom assume the read/write
connection is always open
_close ()
This method is unused as we use persistant connections, letting memcached take care about synchronization.
_exists ($key)
Exists maps to the getter function, as memcached does not support exists checks.
_on_initialize ()
This handler completes the configuration.
_open ($write)
This method is unused as we use persistant connections, letting memcached take care about synchronization.
_put ($key, $data, $timeout)
Parameters
$key
$data
$timeout
Properties
mixed $_abort_on_fail
Whether to abort the request if connection to memcached fails
mixed $memcache_operational
Whether memcached is working
string $_host
The IP to connect to.

\Memcache $memcache
