php javascript重定向问题

我有两个php页面page1.php和page2.php

page1.php使用id参数重定向到page2.php

page2.php？id=8923423672222

page1.php代码

<?
 $id = "4556745767";
 echo "<script language=\"javascript\">function gopage2(){top.window.location.href=\"http://www.example.com/page2.php?id=".$id."\";}setTimeout('gopage2()',1000);</script>";
?>

---

嗯<代码>顶部。窗口…

？？？只需

window…

我需要它来防止页面嵌入到框架中

<?
$id = $_GET['id'];
if($id!='')
{
 section = "section1";
}
else
{
 section = "section2";
}
echo "<script language=\"javascript\">function gosite(){top.window.location.href=\"http://www.example.com/".$section."/\";}setTimeout('gosite()',1000);</script>";
?>
