我在php中有一个代码：
$result = mysql_query($cxn,$sql_query)
$dataset= mysqli_fetch_fields($result);
for ($i = 0; $i < 13; $i++) {
$dataset[$i]->name
}
我想要zend中的上述代码。
这里mysql_fetch_fields（$result）返回给定结果集$result中的字段信息。如何在zend框架中做到这一点？我在谷歌上搜索过，我发现我们可以从特定的表中检索关于列的信息，但从结果集中如何在zend框架中检索？？
这在Zend Framework中目前是不可能的。查看结果集元数据的请求解决方案。您可以尝试使用实验性PDOStatement：：getColumnMeta
UPDATE-注释中的代码示例
sample table structure
table1: id (int), field1 char(3)
table2: id (int), field2 char(3)
<?php
require_once('Zend/Loader/Autoloader.php');
$autoloader = Zend_Loader_Autoloader::getInstance();
// create MySQL database adapter
$db = new Zend_Db_Adapter_Pdo_Mysql(array(
'host' => '127.0.0.1',
'username' => 'test',
'password' => 'test',
'dbname' => 'test'
));
// create temporary table
$result = $db->getConnection()->exec('
CREATE TEMPORARY TABLE myTable
SELECT
t1.id,
t1.field1,
t2.field2
FROM table1 t1
INNER JOIN table2 t2
ON t1.id = t2.id
');
// describe
$info = $db->describeTable('myTable');
var_dump($info);
// drop table
$result = $db->getConnection()->exec('DROP TEMPORARY TABLE myTable');

我发现使用Zend Framework获取关于表的所有元数据非常简单。
- 首先为表创建DbTable模型：定义表类
- 实例化对象：
$table = new Application_Model_DbTable_Table(); - 对该对象调用->info（）：$meta=$table->info（
