如何从数组中回显数据？

Question

I have this array

Array
(
[first_information] => Array
    (
        [0] => 10
        [1] => 12
    )

[rows] => 1
[0] => Array
    (
        [data_1] => 1
        [data_2] => 2
        [data_3] => 3
        [data_4] => 4
        [data_5] => 5
    )

)

How am I supposed to show only the [first_information] content's.

I have tried with this code

foreach($row['first_information'] as $first)  
   echo $first; 

But shows only '12' which is the second element of the array.

Thank you in advance.

You are doing something wrong (not shown in question, probably wrong var). The code below working as expected (http://codepad.org/NDxhEBdY):

$row = array(
    'first_information' => Array(10,12),
    'rows' => 1,
     0 => Array(
        'data_1' => 1,
        'data_2' => 2,
        'data_3' => 3,
        'data_4' => 4,
        'data_5' => 5
    )
);

foreach($row['first_information'] as $first)  
    echo $first;
