php文件出错，网页显示有误。
网站顶端出现如下提示：Warning: Cannot modify header information - headers already sent by (output started at /home/aimeicom/public_html/index.php:4) in /home/aimeicom/public_html/inc/function.php on line 33
Warning: Cannot modify header information - headers already sent by (output started at /home/aimeicom/public_html/index.php:4) in /home/aimeicom/public_html/inc/function.php on line 34
function.php的代码如下：
<?php
require_once "config.php";
require_once 'Taoapi.php';
require_once 'incfunction.php';
date_default_timezone_set('Asia/Shanghai');
$read_data_num = 0;
$arr_app = getoneapp();
$Taoapi_Config = Taoapi_Config::Init();
$Taoapi_Config->setTestMode(false)
->setVersion(2)
->setAppKey($arr_app[0])
->setAppSecret($arr_app[1]);
$Taoapi = new Taoapi;
$Taoapi->Cache->setCacheTime($setCacheTime);
if((time() % 500)==0){
deldir("Apicache",$setCacheTime*60*60);
}
$url_this = "http://".$_SERVER ['HTTP_HOST'].$_SERVER['REQUEST_URI'];
if($rehost == "on"){
$the_host = $_SERVER['HTTP_HOST'];
$request_uri = isset($_SERVER['REQUEST_URI']) ? $_SERVER['REQUEST_URI'] : '';
$siteurlre = str_replace("http://","",$siteurl);
$request_uri = str_replace("index.php","",$request_uri);
if($the_host !== $siteurlre)
{
header('HTTP/1.1 301 Moved Permanently');
header('Location: '.$siteurl.$request_uri);
}
}
?>
33和34行就是最后那两个header。
中间的空白行是否要删除？
别人说了很多很专业的东西，但我看不懂，我想知道怎么改能不让这两条错误提示显示出来，谢谢。index.php的代码如下：
