Memcache functions in PHP
Memcache functions are listed as follows:
Memcache: add? Add a value. if it already exists, false is returned.
Memcache: addServer? Add an available server address
Memcache: close? Disables a Memcache object.
This time to bring you the PHP implementation of the consistency hash algorithm steps, the PHP implementation of the consistency hash algorithm considerations are what, the following is the actual case, together to see.
The consistent hashing
Consistency Ring hash algorithm has a big use is to solve the problem of Memcache server down machine. The goal is to increase or remove the Memcache server, minimizing the impact.
The theory is not introduced, there is too much information on the
PHP calls Memcache to store the session in the following way, remember to need to/usr/local/php/etc/php.ini Session.auto_start = 0 is set to 0, Otherwise, calling the Memcache storage session is not effective. The reason is: when PHP executes the

This article mainly introduces Memcache in PHP. starting from introduction to Memcache, it describes in detail the differences between Memcache and memcached, all PHP Memcache operation methods, and detailed explanations of each operation method,
A major use of the consistent ring Hash algorithm is to solve the Memcache server down machine problem. The purpose is to minimize the impact of a Memcache server after it is added or removed. I will not describe the theory. There is too much
The list of Memcache class functions is as follows:
Memcache::add? Adds a value that returns false if it already exists
Memcache::addserver? Add a server address that is available for use
Memcache::close? Close a Memcache object
