从嵌套数组中检索元素

Question

我正在使用MultipleIterator()迭代两个不同的数组并获取每个元素。

我的代码

$d = new MultipleIterator ();
        $d->attachIterator ( new ArrayIterator ( $tbl_one_data ) );
        $d->attachIterator ( new ArrayIterator ( $tbl_two_data ) );
        foreach ( $d as $data ) {
            print_r($data);
            }

生成以下内容：

我的问题是我如何遍历数组并返回每个元素？例如，我想返回2014-11-06 11:31:58.781018。尝试使用$data[0][0]，但这会返回第一个索引中的所有元素，但我只想要一个元素。

修改

print_r($d);

Answer 1

如果这确实是由print_r输出的那么$ data [0] [1]必须是'2014-11-06 11：31：58.781018'。我用代码测试它：

$data = array(array('1','2014-11-06 11:31:58.781018'));
echo '<pre>';
print_r($data); echo '<br>';
echo 'what we want: '.$data[0][1].'<br>';

otput：

Array
(
    [0] => Array
        (
            [0] => 1
            [1] => 2014-11-06 11:31:58.781018
        )

)

what we want: 2014-11-06 11:31:58.781018

Answer 2

如果您将$ data作为数组，则可以访问该值：2014-11-06 11：31：58.781018 by using，

$date = $data[0][1];
