如何使用PDO从表中获取所有列名？

id         name        age
1          Alan        35      
2          Alex        52
3          Amy         15

我想要的信息是,

id         name        age

编辑:

这是我的尝试,

$db = $connection->get_connection();
$select = $db->query('SELECT * FROM contacts');

$total_column = $select->columnCount();
var_dump($total_column);

for ($counter = 0; $counter < $total_column; $counter ++) {
    $meta = $select->getColumnMeta($counter);
    $column[] = $meta['name'];
}
print_r($column);

然后我明白了,

Array
(
    [0] => id
    [1] => name
    [2] => age
    ...

)
