&ini.descriptions.title;
memcached.sess_lockingbool
Use session locking. Valid values: On, Off, the default is On.
memcached.sess_consistent_hashbool
If set to On, consistent hashing (libketama) is used for session handling. When consistent hashing is used, one can add or remove cache node(s) without messing up too much with existing keys. Default is On.
memcached.sess_binarybool
Use memcached session binary mode. Libmemcached replicas only work if
binary mode is enabled. The default is Off.
memcached.sess_lock_waitint
Session spin lock retry wait time in microseconds. Be careful when
setting this value. Valid values are integers, where 0 is interpreted
as the default value. Negative values result in a reduces locking to a
try lock. The default is 150000.
memcached.sess_prefixstring
Memcached session key prefix. Valid values are strings less than 219
bytes long. The default value is "memc.sess.key."
memcached.sess_number_of_replicasint
Write data to a number of additional memcached servers. This is "poor man's HA" as libmemcached calls it. If this value is positive and sess_remove_failed_servers is enabled when a memcached server fails the session will continue to be available from a replica. However, if the failed memcache server becomes available again it will read the session from there which could have old data or no data at all. Default is 0.
memcached.sess_randomize_replica_readbool
Memcached session replica read randomize.
memcached.sess_remove_failedint
Allow failed memcached server to automatically be removed.
memcached.compression_typestring
Set the compression type, valid values are: fastlz, zlib. The default
is fastlz.
memcached.compression_factorfloat
Compression factor. Store compressed value only if the compression
factor (saving) exceeds the set limit. Store compressed if:
plain_len > comp_len * factor. The default value
is 1.3 (23% space saving).
memcached.compression_thresholdint
The compression threshold. Do not compress serialized values below this
threshold. The default is 2000 bytes.
memcached.serializerstring
Set the default serializer for new memcached objects. Valid values
are: php, igbinary, json, json_array, msgpack.
json
Standard php JSON encoding. This serializer is fast and compact but
only works on UTF-8 encoded data and does not fully implement
serializing. See the JSON extension. Available as of memcached 0.2.0.
json_array
As json, but decodes into arrays. Available as of memcached 2.0.0.
php
The standard PHP serializer.
igbinary
A binary serializer. Available as of memcached 0.1.4.
msgpack
A cross-language binary serializer. Available as of memcached 2.2.0.
The default is igbinary if available, then msgpack if available, then php otherwise.
memcached.use_saslbool
Use SASL authentication for connections. Valid values: On, Off. The
default is Off.
memcached.default_binary_protocolbool
Sets the default memcached protocol for new connections. (To configure the memcached protocol for connections used by sessions, use memcached.sess_binary_protocol instead)
If set to On, the memcached binary protocol is used by default. If set to Off, the memcached text protocol is used. Default is Off
memcached.default_connect_timeoutint
Sets the default memcached connection timeout for new connections. (To configure the memcached connection timeout for sessions, use memcached.sess_connect_timeout instead)
In non-blocking mode this changes the value of the timeout. during socket connection in milliseconds. Specifying -1 means an infinite timeout. Specifying 0 means using the memcached library's default connection timeout. Default is 0.
memcached.default_consistent_hashbool
Sets the default for consistent hashing for new connections. (To configure consistent hashing for session connections, use memcached.sess_consistent_hash instead)
If set to On, consistent hashing (libketama) is used for session handling. When consistent hashing is used, one can add or remove cache node(s) without messing up too much with existing keys default is Off
memcached.sess_binary_protocolbool
Use the memcached binary protocol for memcached sessions (Instead of the text protocol) libmemcached replicas work only if binary mode is enabled. However, certain proxies (such as twemproxy) will work only if the binary protocol is disabled. In older versions of php-memcached, this setting was Off and was called memcached.sess_binary. Default is On with libmemcached 1.0.18 or newer. Default is Off with older version.
memcached.sess_connect_timeoutint
memcached connect timeout value
In non-blocking mode this changes the value of the timeout during socket connection in milliseconds. Specifying -1 means an infinite timeout.
memcached.sess_consistent_hash_typestring
Memcached session consistent hash type. If set to 'ketama', consistent hashing (libketama) is used for session handling (default for php-memcached 3.x) if set to 'ketama_weighted', weighted consistent hashing (libketama) is used for session handling (default for php-memcached 2.x). Default is "ketama".
memcached.sess_lock_expireint
The time, in seconds, before a lock should release itself. Setting to 0 results in the default behaviour, which is to use PHP's max_execution_time. Default is 0.
memcached.sess_lock_retriesint
The number of times to retry locking the session lock, not including the first attempt. Default is 5.
memcached.sess_lock_wait_maxint
The maximum time, in milliseconds, to wait between session lock attempts. The default is 150.
memcached.sess_lock_wait_minint
The minimum time, in milliseconds, to wait between session lock attempts. This value is double on each lock retry until memcached.sess_lock_wait_max is reached, after which any further retries will take sess_lock_wait_max seconds. The default is 150.
memcached.sess_persistentbool
Whether or not to re-use the memcached connections corresponding to the value(s) of session.save_path after the execution of the script ends. Don't use this if certain settings (e.g. SASL settings, sess_binary_protocol) would be overridden between requests. Default is Off.
memcached.sess_remove_failed_serversbool
Allow failed memcached server to automatically be removed. Default is Off. (In previous versions, this setting was called memcached.sess_remove_failed)
memcached.sess_server_failure_limitint
Set this value to enable the server be removed after configured number of continuous times connection failure. Default is 0.
memcached.sess_sasl_passwordstring
Session SASL password
Both username and password need to be set for SASL to be enabled
memcached.sess_sasl_usernamestring
Session SASL username
Both username and password need to be set for SASL to be enabled
memcached.store_retry_countint
The amount of retries for failed store commands.
This mechanism allows transparent fail-over to secondary servers when set/increment/decrement/setMulti operations fail on the desired server in a multi-server environment. the default is 2
