有人遇到mysqli的fetch_assoc()方法出错吗？解决方案

while($row =$rs->fetch_assoc())
{
echo "";
echo "" . $row['FirstName'] . "";
echo "" . $row['LastName'] . "";
echo "" . $row['Age'] . "";
echo "" . $row['HomeTown'] . "";
echo "" . $row['Job'] . "";
echo "";
}

query($query);

/* numeric array */
$row = $result->fetch_array(MYSQLI_NUM);
printf ("%s (%s)\n", $row[0], $row[1]);

/* associative array */
$row = $result->fetch_array(MYSQLI_ASSOC);
printf ("%s (%s)\n", $row["Name"], $row["CountryCode"]);

/* associative and numeric array */
$row = $result->fetch_array(MYSQLI_BOTH);
printf ("%s (%s)\n", $row[0], $row["CountryCode"]);

/* free result set */
$result->close();

/* close connection */
$mysqli->close();
?>

------解决方案--------------------
没有错误信息吗?
看样子是没有打开错误显示功能

那只能是你的关联字段没有和数据库中的对应上。
实在没办法，用预编译处理吧：
PHP code

$sql = "SELECT mid,movName,movType,movStar,movImg,movPlay,director,producter FROM mov_film";
        $stmt = $this->mysqli->prepare($sql);
        $stmt->execute();
        $stmt->store_result();
         $stmt->bind_result($mid,$movName,$movType,$movStar,$movImg,$movPlay,$director,$producter);
        $rows = $stmt->affected_rows;
        if ($rows > 0){
            $arrMovie = array();
            while($stmt->fetch()){
                //将文件名从路径中取出并转换为相对路径
                $movImg = "../../images/".basename($movImg);
                //截取文件名
                $arrStr = explode(".",basename($movPlay));
                $movPlay = "../../videos/".$arrStr[0];

                $arr = array(
                    "mid" => $mid,
                    "movName" => $movName,
                    "movType" => $movType,
                    "movStar" => $movStar,
                    "movImg" => $movImg,
                    "movPlay" => $movPlay,
                    "director" => $director,
                    "producter" => $producter
                );
                array_push($arrMovie,$arr);
            }
            return $arrMovie;
        }
