这篇文章给大家介绍的内容是关于php TAL模板引擎语法,内容很详细,有需要的朋友可以参考一下,希望可以帮助到大家。
本文档的使用到的数据($talData)
//定义talData变量 $talData = array(); $talData['title'] = 'title1'; $talData['key'] = 'key1'; $talData['href'] = 'xxx.html'; $talData['html'] = '<h1>h1标题</h1>'; $talData['fun'] = function($key=''){ return $key === 'key1'? true : false; }; //两维数组 $talData['list1'] = array( array('id'=>'1', 'title'=>'标题1'), array('id'=>'2', 'title'=>'标题2'), array('id'=>'3', 'title'=>'标题3'), array('id'=>'4', 'title'=>'标题4') );
//输出的数据结构 {"title":"title1","key":"key1","href":"xxx.html","html":" h1\u6807\u9898<\/h1>","fun":{},"list1":[{"id":"1","title":"\u6807\u98981"},{"id":"2","title":"\u6807\u98982"},{"id":"3","title":"\u6807\u98983"},{"id":"4","title":"\u6807\u98984"}]}
define 定义变量
condition
repeat
content or replacae
attributes 属性
omit-tag
