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 />

Copy after login

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 />}

Copy after login
