这篇文章主要介绍了thinkphp路由规则使用示例详解和伪静态功能实现(apache重写),需要的朋友可以参考下
复制代码 代码如下: <?php //thinkphp 路由定义规则 $route = array( 'news/:action/:year\d/:month/:day'=>'news/read?year=:2&month=:3&day=:4', 'news/:action^delete|update|insert/:year\d/:month/:day'=>array( 'news/read?extra=:2&status=1','year=:2&month=:3&day=:4'), );
$url = 'http://www.test.com/index.php/news/read/2012/2/21/extraparam/test.html';
//后缀名 $extension = 'html';
//可知: $_SERVER['PATH_INFO'] = 'news/read/2012/2/21/extraparam/test.html'; $regx = 'news/read/2012/2/21/extraparam/test.html';
//循环匹配路由规则 foreach($route as $key=>$value){ //如果匹配成功,则不继续匹配 if(parseUrlRule($key,$value,$regx,$extension)) break; }
//运行结果: 打印$_GET //Array // ( // [actionName] => read // [moduleName] => news // [extra] => 2012 // [status] => 1 // [extraparam] => test // [year] => 2012 // [month] => 2 // [day] => 21 // [finalUrl] => news/read?extra=2012&status=1&extraparam=test&year=2012&month=2&day=21 // ) // [Finished in 0.6s]
//相当于访问: http://www.test.com/news/read?extra=2012&status=1&extraparam=test&year=2012&month=2&day=21
//在部署时会把index.php隐藏,开启apache的重写模块 //重写规则 : RewriteRule ^(.+)$ /index.php/$1 //开启后,apache会自动把 http:/www.test.com/news/read/2012/2/21/extraparam/test.html转换为 http:/www.test.com/index.php/news/read/2012/2/21/extraparam/test.html
