关于Setcookie问题

<?php
$value = 'something from somewhere';

setcookie("TestCookie", $value);
setcookie("TestCookie", $value, time()+3600);  /* expire in 1 hour */
setcookie("TestCookie", $value, time()+3600, "/~rasmus/", ".example.com", 1);
echo"5665453133";
?>
<a href="Untitled-2.php">saffsadsdaf</a>
<form id="form1" name="form1" method="post" action="Untitled-2.php">
  <table width="550" border="1" cellspacing="0" cellpadding="0">
    <tr>
      <td> </td>
      <td> </td>
      <td><input type="submit" name="Submit" value="提交" /></td>
    </tr>
  </table>
</form>



在本地预览时没有错，可是传到网上的空间时提示有错，提示如下：

为什么有了提交按钮就有错误呢？应该怎么改？

setcookie之前不能有任何输出
