/**
|
||
* WP Chinese Switcher Plugin main file
|
||
*
|
||
* 为Wordpress增加中文繁简转换功能. 转换过程在服务器端完成. 使用的繁简字符映射表来源于Mediawiki.
|
||
* 本插件比较耗费资源. 因为对页面内容繁简转换时载入了一个几百KB的转换表(ZhConversion.php), 编译后占用内存超过1.5MB
|
||
* 如果可能, 建议安装xcache/ eAccelerator之类PHP缓存扩展. 可以有效提高速度并降低CPU使用,在生产环境下测试效果非常显着.
|
||
*
|
||
* @package WPCS
|
||
* @version see wpcs_VERSION constant below
|
||
* @TODO 用OO方式重写全部代码, 计划1.2版本实现.
|
||
* @link http://wordpress.org/plugins/wpchinese-switcher Plugin Page on wordpress.org, including guides and docs.
