Question

我试图在html表中显示整个mysql表。到目前为止，我已经找到了以下代码，用于显示字段：

<?php
   $con=mysqli_connect("example.com","peter","abc123","my_db");
   // Check connection
   if(mysqli_connect_errno()) {
      echo "Failed to connect to MySQL: " . mysqli_connect_error();
   }

   $result = mysqli_query($con,"SELECT * FROM Persons");

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

   while($row = mysqli_fetch_array($result)) {
      echo "<tr>";
      echo "<td>" . $row['FirstName'] . "</td>";
      echo "<td>" . $row['LastName'] . "</td>";
      echo "</tr>";
   }
   echo "</table>";

   mysqli_close($con);
?>

有没有办法可以显示所有列/行，而无需键入所有列名称

echo "<td>" . $row['FirstName'] . "</td>";

Answer 1

如果您要显示所有列，则可以执行此操作。或者，您可以有条件地添加过滤器。

但是，由于您似乎对Web开发不熟悉，我会以简单的方式进行。

<?php
$con=mysqli_connect("example.com","peter","abc123","my_db");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}

$result = mysqli_query($con,"SELECT * FROM Persons");

echo "<table border='1'>";

$i = 0;
while($row = $result->fetch_assoc())
{
    if ($i == 0) {
      $i++;
      echo "<tr>";
      foreach ($row as $key => $value) {
        echo "<th>" . $key . "</th>";
      }
      echo "</tr>";
    }
    echo "<tr>";
    foreach ($row as $value) {
      echo "<td>" . $value . "</td>";
    }
    echo "</tr>";
}
echo "</table>";

mysqli_close($con);
?>

Answer 2

你可以做这样的事情

while($row = mysqli_fetch_array($result))
{
echo "<tr><td>" . implode("</td><td>",$row) . "</td></tr>";
}

为了尝试使用数据库，请将以下代码粘贴到phpfiddle.org工作区（首先在主页中检查MySQLi库）。

<?php /** * Mysqli initial code * * User permissions of database * Create, Alter and Index table, Create view, and Select, Insert, Update, Delete table data * * @package PhpFiddle * @link http://phpfiddle.org * @since 2012 */ require "util/public_db_info.php"; $short_connect = new mysqli($host_name, $user_name, $pass_word, $database_name, $port); $sql = "SELECT * FROM `books` WHERE title='The Martian'"; $result = $short_connect->query($sql); if (($result) && ($result->num_rows > 0)) { echo "<table>"; //convert query result into an associative array while ($row = $result->fetch_array()) { echo "<tr><td>" . implode("</td><td>",$row) . "</td></tr>"; } echo "</table>"; $result->free(); } $short_connect->close(); ?>

要获得这样的垂直表：

PHP代码：

$idProduct = $conexion->real_escape_string($_GET['planId']);
$result = $conexion->query("SELECT * FROM `g4s_products` WHERE id_product = '".$idProduct."'");
if ($result->num_rows > 0) {
    $html = '';
    while ($row = $result->fetch_assoc()) {
        $html .= '<div class="ppalDiv">' .
            '<p class="subtitleDetails"><b>Main Benefits</b></p>' .
            '<p class="textDetails">' . $row["description"] . '</p>' .
            '</div>' .
            '<div class="ppalDiv">' .
            '<p class="subtitleDetails"><b>Benefits Highlights</b></p>';

        echo $html;

        echo "<table>";
        foreach ($row as $key => $value) {
            echo "<tr>";
            echo "<th>" . $key . ":</th>";
            echo "<td>" . $value . "</td>";
            echo "</tr>";
        }

        echo "</table>";
    }
}
mysqli_close($conexion);

CSS代码：

table, th, td {
border: 1px solid black;
border-collapse: collapse;

}

th, td {
    padding: 5px;
    text-align: left;
}

完成了。享受
