先取得表的列名。SHOW COLUMNS FROM tbl_name

<code>$data = $mysql->query("select * from $table_name where id = $id");
foreach($data as $k){//这里是结果集
    foreach($k as $kk=>$vv){
        echo $kk.':'.$vv.'<br>';//避开键名写死的情况
    }
}</code>

参考的官方例子

A nice feature of PDO::query() is that it enables you to iterate over
the rowset returned by a successfully executed SELECT statement.

<code><?php function getFruit($conn) {
    $sql = 'SELECT name, color, calories FROM fruit ORDER BY name';
    foreach ($conn->query($sql) as $row) {
        print $row['name'] . "\t";
        print $row['color'] . "\t";
        print $row['calories'] . "\n";
    }
}
?>
