从数据库获取表上方的名称列

Question

我编写的代码将根据查询的结果集动态生成表。每行中的每个字段都放在自己的单元格中。如何在适当的列上添加列名作为标题？

我的代码：

$db = new mysqli("...", "...", "", "...");
$query = "SELECT * from customer ";
if ($result = $db->query($query)) {

    /* Get field information for all columns */
    while ($finfo = $result->fetch_field()) {
        printf("%s\n", $finfo->name);
    }
    $result->close();
}


$db = new mysqli('...', '...', '...', '...');
if($db->connect_errno > 0){
    die('Unable to connect to database [' . $db->connect_error . ']');
}
$sql = "SELECT * from ...";
if(!$result = $db->query($sql)){
    die('There was an error running the query [' . $db->error . ']');
}
echo "<table class='table'>";
while($row = $result->fetch_assoc()){
echo "<tr class='info'>
                <td>" . $row['COLUMN1'] . "</td>
                <td>" . $row['COLUMN2'] . "</td>
               <td>" . $row['COLUMN3'] . "</td>
                <td>" . $row['COLUMN4'] . "</td>
               <td>" . $row['COLUMN5'] . "</td>
               <td>" . $row['COLUMN6'] . "</td>
            </tr>";  
}
echo "</table>";

?>

您只需打开1个DB连接即可。您可以在运行的查询上使用fetch_field，而无需迭代结果集的行。我添加的所有空格都是可选的。

    $db = new mysqli("...", "...", "", "...");

    if($db->connect_errno > 0){
        die('Unable to connect to database [' . $db->connect_error . ']');
    }


    $sql = "SELECT * from ...";
    if(!$result = $db->query($sql)){
        die('There was an error running the query [' . $db->error . ']');
    }

    echo "
<table class='table'>
    <thead>
        <tr>";
    /* Get field information for all columns */
    while ($finfo = $result->fetch_field()) {
        echo "
        <th>" . $finfo->name . "</th>";
    }
    echo "
        </tr>
    </thead>
    <tbody>";
    while($row = $result->fetch_assoc()){
    echo "<tr class='info'>
            <td>" . $row['COLUMN1'] . "</td>
            <td>" . $row['COLUMN2'] . "</td>
            <td>" . $row['COLUMN3'] . "</td>
            <td>" . $row['COLUMN4'] . "</td>
        </tr>";  
    }
    echo "
    </tbody>
</table>";
