pdo如何获取全部字段啊??

本帖最后由 rainxies 于 2013-03-11 13:08:21 编辑 我只找到mysql方法的,用pdo的话,下面的代码该如何写啊?谢谢
<br />
$result = mysql_query("SELECT * FROM table");<br />
$fields = mysql_num_fields($result);<br />
for ($i=0; $i < $fields; $i++) {<br />
   $names[] = mysql_field_name($result, $i);<br />
}<br />
print_r($names);<br />


mysql_num_fields我有找到PDOStatement下面有个columnCount()函数
mysql_field_name我硬是没找到对应的………

还是有另外的办法??

try {<br />
  $dbh = new PDO('mysql:host=localhost;dbname=test', 'root', '');<br />
  $stmt = $dbh->query("select * from tbl_name");<br />
  for($i=0; $i<$stmt->columnCount(); $i++) {<br />
    echo $stmt->getColumnMeta($i)['name'], PHP_EOL;//php5.4适使用,之前的版本需拆成两句<br />
  }<br />
} catch (PDOException $e) {<br />
  die("Error!: " . $e->getMessage());<br />
}
