从本地（100%工作）移动到托管时的Bizzare PHP行为。有些代码工作，有些不工作

我一直在用PHP在MacBookPro上本地安装MAMP来构建一个网站。昨天，我终于设法完成了所有工作，所以我决定购买一些Web空间，并使用与MAMP（PHP5.3，MySQL）上的本地安装完全相同的设置来托管文件

当我移动文件并测试站点时，我得到了一个非常奇怪的错误。大多数代码都在工作，但是，代码中有一些部分已损坏，但以一种非常不寻常的方式。我会尽力解释的

注：此图可能很好地显示了错误。我屏蔽了一些私人内容

代码的第一位是：

if ($currentpage > $totalpages) {
   // set current page to last page
   $currentpage = $totalpages;
} // end if
// if current page is less than first page...
if ($currentpage < 1) {
   // set current page to first page
   $currentpage = 1;
} // end if

// the offset of the list, based on current page 
$offset = ($currentpage - 1) * $rowsperpage;

$sql = "SELECT * FROM message,thumbsup_items WHERE message.id = thumbsup_items.name AND message.date BETWEEN DATE_SUB(NOW(), INTERVAL 7 DAY) AND NOW() ORDER BY votes_down DESC LIMIT $offset, $rowsperpage";
$result = mysql_query($sql, $conn) or trigger_error("SQL", E_USER_ERROR);
$dest = "http://twitter-badges.s3.amazonaws.com/t_mini-b.png";
$dest2 = "images/fb-small.png";
$url="http://dfwm.ws";
while ($row = mysql_fetch_assoc($result)) 

{

    ?>

我得出的结论是，如果这是一个与运算符有关的错误，就像这两次都发生过的那样，那么它肯定不会显示任何内容，而不是从PHP标记中出来并将其显示为HTML？（图中显示了问题开头的内容）

我真的很想得到一些帮助，因为我已经为此绞尽脑汁好几个小时了

谢谢Martin和Naltharial。我想知道是不是这样，但不确定。
