Question

请教一个我这个php程序写的对不对.

<?php
$baidu=$_SERVER['HTTP_HOST'];
switch($baidu){
case "http://www.gaosugongu.com.cn":
echo "<script language = "javascript">";
echo "window.location.href ="bbs/index.php"";
echo "</script>";
break;
case "http://www.gaosugongu.com":
echo "<script language = "javascript">";
echo "window.location.href ="index.php"";
echo "</script>";
break;
default:
echo "<script language = "javascript">";
echo "window.location.href ="index.php"";
echo "</script>";
break;
}?>
实际上我相达到这个的功能跟具访问人输入的网址转到不同页面!
跳转不成功

Answer 1

有几个问题

第一,,echo js重定向语句重复出现在程序里面，可以参考上面的程序写法

第二,,echo 后面的旅顺法是错的
echo "<script language = "javascript">";
echo "window.location.href ="index.php"";
echo "</script>";
如果你跑，，程序一定会报错正确的应该是
echo '<script language = "javascript">';
echo 'window.location.href ="index.php"';
echo '</script>';
或者把双引号里面的双引号作\"转义
还有，，这个第二个case是多余的

对了$_SERVER['HTTP_HOST']取到的值是不带http://的,,,
比如http://www.gaosugongu.com只能取到www.gaosugongu.com

Answer 2

<?php

$host = $_SERVER['HTTP_HOST'];

$to_url = '';

switch($host){

case 'http://www.gaosugongu.com.cn':

$to_url = 'bbs/index.php';
break;

case "http://www.gaosugongu.com":

$to_url = 'index.php';
break;

default:

$to_url = 'index.php';
break;

}

if($to_url){
header("Location:$to_url");
}

?>
//这个看起来比较清爽,,,,,简洁....

Answer 3

问题出在case "http:xxxxxx" 后面少了个冒号 应该是

case "http:xxxxxx":
xxxxxxxxxx;
break;

Answer 4

没这个必要用JAVASCRIPT,直接用PHP的location.href跳转不行吗?
