使用纯php代码实现页面伪静态的方法_PHP

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);
}
