我猜你的 mysql_query 有错误。请参阅 mysql_query 的文档。

对于 SELECT、SHOW、DESCRIBE、EXPLAIN 和其他返回结果集的语句，mysql_query() 成功时返回资源，错误时返回 FALSE。

所以，我猜你的 $query 变量中有一个 FALSE。

在获取行之前始终检查输出。您的查询中有一些错误。

尝试这样做：

if(!$query)
{
echo mysqli_error();
}else{
  while( $row = mysqli_fetch_array( $query ) )
     {
   //fetch rows
     }

这样做你会知道确切的错误。（避免使用mysql，而是使用mysqli）

您的 SQL 查询错误。

SELECT * FROM ocwconnections WHERE FormDistributionDate BETWEEN `fromdate` AND `todate`

由 ` 包围的字符串被视为列名。看起来你想要一个变量。

$fromdate = $_GET['fromdate'];
$todate= $_GET['todate'];
$sql = "SELECT * FROM ocwconnections WHERE `FormDistributionDate` BETWEEN $fromdate AND $todate ";

这应该有效（未经测试）。

请记住，这会将您的脚本打开到 SQL 注入。切换到mysqli_*函数或 PDO 并使用准备好的语句。

您忘记对此发表评论var_dump($query); exit;。在那之后，它应该工作。
