Question

我正在尝试从phpmyadmin获取第一行。在尝试以不同的方式进行操作后，我想问一下。现在，问题在于它正在不断刷新浏览器。

我尝试添加一个死，但是我在mysqli / php方面不是很好

    $sql2="SELECT * FROM stellingen WHERE REGIOID=1;";
    $records2 =  mysqli_query($con, $sql2);

    $row = mysqli_fetch_assoc($records2);

    while ($stellingen = mysqli_data_seek($records2, 0)){
        echo "<p>".$stellingen['Stelling']."</p>";
    }

我希望php能够获取第一个数据。在循环的情况下，下一个数据将不需要在页面的后面。

<div class="stellingen">
    <div class="stelling-wrapper" id="btn1">
        <img src="images/button.svg" alt="Show more..." class="btn" id="bton">
        <p type="button" class="stelling">
<?php
    $sql2="SELECT * FROM stellingen WHERE REGIOID=1;";
    $records2 =  mysqli_query($con, $sql2);

    $row = mysqli_fetch_assoc($records2);

    while ($stellingen = mysqli_data_seek($records2, 0)){
        echo "<p>".$stellingen['Stelling']."</p>";
    }

    /*
    if ($recordscheck2 > 0){
        while ($stellingen = mysqli_fetch_assoc($records2)){
            echo "<p>".$stellingen['Stelling']."</p>";
        }
    }*/
?>
</div>
<div id="p1">
    <table id="tabel" border=1px class="data">
    <tr>
        <th>Title</th>
        <th>Source</th>
        <th>Weight</th>
        <th>Date</th>
    </tr>

<?php
$sql1="SELECT * FROM stelling WHERE stelling_iD=1;";
$records1 =  mysqli_query($con, $sql1);
$recordscheck = mysqli_num_rows($records1);

if ($recordscheck > 0){
    while ($stelling = mysqli_fetch_assoc($records1)){
        echo "<tr>";
            echo "<td>".$stelling['Title']."</td>";
            echo "<td>".$stelling['Source']."</td>";
            echo "<td>".$stelling['Wheight']."</td>";
            echo "<td>".$stelling['Timer']."</td>";
        echo "</tr>";
    }
}
?>
    </table>
</div>

Okey，所以您在mysqli_data_seek()循环中使用while()，这是错误的...

<?php

if($result = mysqli_query($con, "SELECT * FROM stellingen WHERE REGIOID=1;")) {

    mysqli_data_seek($result, 0);

    $row = mysqli_fetch_assoc($result);

    echo "<p>{$row["Stelling"]}</p>";

}

?>

应该为您工作。

[编辑]我更正了变量名。

从数据库获取第一行会连续刷新页面
