使用纯php代码实现页面伪静态的方法

if(1==URLROLE){  $nav=$_SERVER["REQUEST_URI"];  $script_name=$_SERVER["SCRIPT_NAME"];  $nav1=ereg_replace(".html","",substr(ereg_replace("$script_name","",urldecode($nav)),1));  $vars = @explode("/",$nav1);  $_url = array_chunk($vars,2);  $_GET['m'] = $vars[0]?$vars[0]:'index';  //如果没有参数，默认访问index类库的index方法  $_GET['a'] = $vars[1]?$vars[1]:'index';  unset($_url[0]);  if($_url){    foreach($_url as $key=>$val){      @$_GET[$val[0]] = $val[1];    }  }//var_dump($_GET);}
