     $date_title=$date;
     $date_begin =$date;

     $date_begin=$date_begin.'-00';

Answer 1

在您向网页输出任何内容后，您无法使用标题重定向。使用类似这样的东西代替javascript替代：

else {
    echo("<script>location.href = 'www.myurlhere.com';</script>");
}

Answer 2

<?php 
if(!isset($_GET["date"])){
header("Location: http://newsite");
}
$date=$_GET["date"];
?>

正如macroman指出的那样，只有当它位于页面顶部，第一个或回声之前时才有效。
