 mysql_select_db($mysql_database, $conn );

 if (isset($_POST['login'])){

//$un = $_POST['name'];
$em = $_POST['email'];
$pw = $_POST['pass'];
//$un = mysql_real_escape_string($un);
$em = mysql_real_escape_string($em);
$pw = mysql_real_escape_string($pw);
 $query = "SELECT * FROM Register WHERE email = '$em' AND pass = '$pw'";
 //$query = "INSERT INTO Register (name,email,pass) VALUES ('$un','$em','$pw')";

 $result = mysql_query($query) or die("Unable to verify user because : " . mysql_error());  


// Check username and password match

发送任何输出后，您无法调用标头功能。访问http://www.w3schools.com/php/func_http_header.asp

<!DOCTYPE HTML>
<html>
<head>
<meta charset="utf-8">
<title>MyCloud-Login</title>

我似乎还记得空白行也会导致问题。移动顶部并摆脱空白行，然后重试。可能还有其他问题，但这就是其中之一。
