如何使用PHP从mySQLi查询中回显每一行?

问题描述：

以下查询返回广告系列表中所有user_id为1的行:

The following query returns all rows from the campaign table that have the user_id of 1:

SELECT * FROM campaign WHERE user_id=1

在测试的情况下，这是两个结果.我如何能够从每一行中回显设置的列.例如，我想从每个结果中回显campaign_name.我尝试了各种方法，但是没有成功.

In the case of testing this is two results. How would I be able to echo a set column from each of the rows. For example, I want to echo the campaign_name from each of the results. I have tried various methods however, I have had no success.

我的最终目标将是这样:

My end goal would be something like this:

 <?php foreach($queryRow as $row) { ?>
                         <li>
                            <a>
                                <div>
                                    <p><?php echo($row['campaign_name']); ?></p>
                                    <p>
                                        Description Text
                                    </p>
                                </div>
                            </a>
                        </li>
 <?php } ?>

我对此一无所知，如果我的预期结果完全不正确，我深表歉意...

I'm quite at lost with this so I apologise if my intended result is completely off...

答

尝试一下:

$qry = "SELECT * FROM campaign WHERE user_id=1";
$res = mysqli_query($conn, $qry);

if(mysqli_num_rows($res) > 0)   // checking if there is any row in the resultset
{
    while($row = mysqli_fetch_assoc($res))  // Iterate for each rows
    {
    ?>
        <li>
            <a>
                <div>
                    <p><?php echo($row['campaign_name']); ?></p>
                    <p>
                        Description Text
                    </p>
                </div>
            </a>
        </li>
    <?php
    }
}

它将对结果集中的每一行进行迭代.

It will iterate for each row in the resultset.
