Step 9b: Using the Sundown PECL extension
The markup system in FOSCommentBundle is flexible and allows you to use anysyntax language that a parser exists for. PECL has an extension for markdown parsing called Sundown, which is faster than pure PHP implementations of a markdown parser.
FOSCommentBundle功能包的标识系统是灵活的，它允许您使用现存任何语法语言的解析器。PECL有一个被称为Sundown的markdown解析扩展，它是比纯PHP更快的markdown解析实现。
FOSCommentBundle doesnt ship with a bridge for this extension, but it is trivial to implement.
FOSCommentBundle没有与该扩展相关的桥，但实现它易如翻掌。
First, you will need to use PECL to install Sundown.
