Question

我仍然是MySQL / PHP的新手，我正在尝试制作将遍历整个SQL表的代码。我能够做到这一点，为了清理我想要使用html表存储值，使事情看起来更整洁。我尝试将HTML代码添加到字符串中，该字符串打印在HTML部分代码的底部，但表格边框不显示。我做错了什么，我该如何解决这个问题？输出的代码和屏幕截图都在下面：

<?php

    include("connection.php");

    $query= "SELECT * FROM schedule";

    $result = mysqli_query($link, $query);

    $scheduletext="<table>";

    if($result = mysqli_query($link, $query)) {

        while ($row=mysqli_fetch_array($result)) {

            $scheduletext="<tr><td>".$scheduletext.$row[1]."</td>";

            $scheduletext="<td>".$scheduletext.$row[2]."</td>";

            $scheduletext="<td>".$scheduletext.$row[3]."</td>";

            $scheduletext="<td>".$scheduletext.$row[4]."</td></tr>";

        }
    }
    $scheduletext=$scheduletext."</table>";

?>

正如@mister martin在评论中所说，使用点来连接你的字符串

$scheduletext ="<table>";

if($result = mysqli_query($link, $query)) {

    while ($row=mysqli_fetch_array($result)) {

        $scheduletext .="<tr><td>".$scheduletext.$row[1]."</td>";

        $scheduletext .="<td>".$scheduletext.$row[2]."</td>";

        $scheduletext .="<td>".$scheduletext.$row[3]."</td>";

        $scheduletext .="<td>".$scheduletext.$row[4]."</td></tr>";

    }
}
$scheduletext .="</table>";
