php - 在 html/php 表中显示 mysql 数据库的结果

Question

嗨，我有一个页面，可以在其中查看 mysql 数据库的数据输出。效果很好。但它并不时尚。所以我决定放入一个html <table>标签。但是它没有显示数据。

我尝试过添加

<td> </td>行之间等，但它会停止解析代码。

<?php
    $servername = "******";
    $username = "root";
    $password = "********";
    $dbname = "test2";

    // Create connection
    $conn = new mysqli($servername, $username, $password, $dbname);
    // Check connection
    if ($conn->connect_error) {
         die("Connection failed: " . $conn->connect_error);
    }

    $sql = "SELECT first_name, last_name, email FROM person_list";
    $result = $conn->query($sql);



    //display table
    echo "<table border='1'>
    <tr>
    <th>Firstname</th>
    <th>Lastname</th>
    <th>Email</th>
    </tr>";

           if ($result->num_rows > 0) {
         // output data of each row

         while($row = $result->fetch_assoc()) {
           echo
     "<br>   ". $row["first_name"]. " "
                                   . $row["last_name"] ." "
                                    . $row["email"] ." " ;
        }
    }
     else {
         echo "0 results";
    }

    echo "</table>";
    $conn->close();
    ?>

试试这个，如果它适合你..

echo "<table border='1'>
    <tr>
    <th>Firstname</th>
    <th>Lastname</th>
    <th>Email</th>
    </tr>";

       if ($result->num_rows > 0) {
     // output data of each row

     while($row = $result->fetch_assoc()) {
       echo "<tr>";
       echo "<td>". $row["first_name"] . "</td>";
       echo "<td>". $row["last_name"] . "</td>";
       echo "<td>". $row["email"] . "</td> " ;
       echo "</tr>";
    }
}
echo "</table>";
