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:


//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: ?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
