thinkphp路由规则使用示例详解

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  代码如下:<?php //thinkphp 路由定义规则  $route = array(  'news/:action/:yeard/:month/:day'=>'news/read?year=:2&month=:3&day=:4',    'news/:action^delete|update|insert/:yeard/: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/$1 //开启后，apache会自动把 http:/www.test.com/news/read/2012/2/21/extraparam/test.html转换为 http:/www.test.com/index.php/news/read/2012/2/21/extraparam/test.html /** *  @$rule  string    路由规则    *  @$route string    规则映射的新地址 *  @$regx  string    地址栏pathinfo字符串 *  @$extension stirng  伪静态拓展名 *  return  bool  */function parseUrlRule($rule,$route,$regx,$extension=null){   //去掉后缀名   !is_null($extension) && $regx = str_replace('.'.$extension,'',$regx);    //把路由规则和地址,分割到数组中，然后逐项匹配   $ruleArr = explode('/',$rule);   $regxArr = explode('/',$regx);    //$route以数组的格式传递，则取第一个   $url = is_array($route) ?
