如果有正确的结果，我需要回显一个下载按钮，但当我回显下载按钮时，它决定回显超过1.如何更正？继承我的代码：

<?php
    $u = $_SESSION["username"];

    $getscripts = $conn->prepare("SELECT * FROM project_sa");
    $getscripts->execute();
    while ($row = $getscripts->fetch(PDO::FETCH_BOTH)) {

        $sec = $conn->query('SELECT * FROM us WHERE username="wafflezzz"');
        $sec->execute();

        while ($rowx = $sec->fetch(PDO::FETCH_BOTH)) {
            $checker = $rowx[$row["script_title"]];
            if ($checker == $row["script_title"]) {

                $geturl = $conn->prepare("SELECT * FROM project_sa WHERE script_title='$checker'");
                $geturl->execute();
                while ($row = $geturl->fetch(PDO::FETCH_BOTH)) {

                    echo '
                      <form method="post" action="dl.php">
                          <input name="bname" value="<?php echo $branded_m_img_url; ?>" hidden></input>
                          <input type="submit" class="ui huge button" value="Download"></input>
                      </form>';
                }

            }

        }

    }

?>

当数据库中只有1个条目时，它会返回大约2个已损坏的重复条目！

＆＃34;你有嵌套的while循环，这就是为什么你得到重复的条目，你也在内部while循环中覆盖$ row - Alon Eitan昨天＆＃34;

在我解决之后，它起作用了！
