if(!isset($_SERVER['PATH_INFO'])) {
$types = explode(',',C('URL_PATHINFO_FETCH'));
foreach ($types as $type){
if(0===strpos($type,':')) {// 支持函数判断
$_SERVER['PATH_INFO'] = call_user_func(substr($type,1));
break;
}elseif(!empty($_SERVER[$type])) {
$_SERVER['PATH_INFO'] = (0 === strpos($_SERVER[$type],$_SERVER['SCRIPT_NAME']))?
substr($_SERVER[$type], strlen($_SERVER['SCRIPT_NAME'])) : $_SERVER[$type];
break;
}
}
}当$_SERVER['PATH_INFO']未设置的时候，就从配置中读取3个$_SERVER变量，分别是ORIG_PATH_INFO,REDIRECT_PATH_INFO,REDIRECT_URL这3个变量分别怎么用的，上网查了半天也没有资料
