Php 而在数据中循环两次

所以我有这个代码，我已经为此烦恼了好几个小时了，我和我的朋友都找不到解决方案。它根据从数据库中提取的递减ID显示评论。这是一种无休止滚动的脚本类型，用于消除分页。出于某种原因，当我点击页面底部并运行脚本时，while循环在数据中迭代了两次。所以如果它应该显示评论ID 5-10，那么它会显示10,9,8,7,6,5,10,9,8,7,6,5；而不是10，9，8，7，6，5。这将是一个非常大的代码位，但我希望你能帮助我解决我的问题。 提前谢谢

您是否也确定数据库中没有损坏？你可以试试看

while ($review_row = mysql_fetch_assoc($mysqlQuery)) {
 echo $review_row['review_title'] . "<br />";
}

while（$review\u row=mysql\u fetch\u assoc（$mysqlQuery））{
echo$review_row['review_title']。“
”；
}
您可以发布调用/发布到此脚本的代码吗？正如其他人所说，这段代码很可能被调用了两次

另外，如果直接在数据库中运行此查询，将返回什么

SELECT * 
FROM `reviews` 
WHERE `review_id` < (insert the id here) 
ORDER BY `review_id` DESC 
LIMIT 0, 10

选择*
来自“评论”
其中“review\u id”<（在此处插入id）
订单由'review_id'描述
限制0,10
如果循环两次，则脚本可能实际运行了两次，这可能是因为重写规则。我不确定是否理解。你能给我一个重写规则的例子吗？如果你不知道它是什么，那肯定不是问题。如果你的web服务器被设置为重定向请求，并且这样做不正确，可能会导致对脚本的两次调用。阅读您的web服务器日志。您是否看到此脚本的每次调用都有两行？@user1371489重写规则通常在
.htaccess
中找到，并指示浏览器转到与其最初发送的URL不同的URL。这只会返回审阅标题，这完全正常，问题是，它会返回两次。一切正常，显示完美，但运行/显示两次。因此，如果查看_title=“apple Iphone”，那么对于上述代码，它将返回：appleIphone
appleIphone
。当然，在包含的脚本中没有其他“echo”？
