LXXV. Memcache Functions簡介Memcache module provides handy procedural and object oriented interface to memcached, highly effective caching daemon, which was especially designed to decrease database load in dynamic web applications. This module doesn't have native support of multiple servers, but you still can implement it yourself in your application. Establish several memcached connections, set priority level for each server etc. More information about memcached can be found at http://www.danga.com/memcached/. 需求This module uses functions of zlib to support on-the-fly data compression. Zlib is required to install this module. PHP 4.3.3 or newer is required to use the memcache extension. 安裝本 PECL 增加未綁定於 PHP 中。 進一步訊息例如新版本,下載,源程式,維護者訊息以及更新日誌可以在此找到: http://pecl.php.net/package/memcache. In order to use these functions you must compile PHP with Memcache support by using the --enable-memcache[=DIR] option. Windows users will enable php_memcache.dll inside of php.ini in order to use these functions. 可以從 PHP 下載頁面或是 http://snaps.php.net/ 下載此 PECL 增加的 DLL 檔案。 預定義常量表格 1. MemCache Constants
運行時配置本增加模組在 php.ini 中未定義任何配置選項。 資源類型There is only one resource type used in memcache module - it's the link identifier for a cache server connection. 範例
In the above example, an object is being saved in the cache and then retrieved back. Object and other non-scalar types are serialized before saving, so it's impossible to store resources (i.e. connection identifiers and others) in the cache.
