cakephp how to group file data when upload multiple file - cakephp-2.2

Question

I use cakephp FormHelper to generate html form code.
echo $this->Form->create('newGallery.', array('type'=>'file'));
echo $this->Form->input('Photos',array(
'type' => 'file',
'label' => 'Photos (jpg,png,gif)',
'name' => 'upload[]',
'required',
'multiple'
));
echo $this->Form->end('Create');
but result is
Array
(
[upload] => Array
(
[name] => Array
(
[0] => Pic1.jpg
[1] => Pic2.jpg
)
[type] => Array
(
[0] => image/jpeg
[1] => image/jpeg
)
[tmp_name] => Array
(
[0] => C:\wamp\tmp\phpB073.tmp
[1] => C:\wamp\tmp\phpB084.tmp
)
[error] => Array
(
[0] => 0
[1] => 0
)
[size] => Array
(
[0] => 216302
[1] => 107102
)
)
)
I need to group the data of the same file so that i can deal with by using foreach loop. This is the result i need
Array
(
[upload] => Array
(
[0] => Array
(
[name] => Pic1.jpg
[type] => image/jpeg
[tmp_name] => C:\wamp\tmp\phpB073.tmp
[error] => 0
[size] => 216302
)
[1] => Array
(
[name] => Pic2.jpg
[type] => image/jpeg
[tmp_name] => C:\wamp\tmp\phpB084.tmp
[error] => 0
[size] => 107102
)
)
)

I think this can help you :)
/* create new empty array */
$result=array();
/* create new index */
$i=0;
/* foreach in your $upload or other array */
foreach($upload['upload'] as $key => $val){
foreach($val as $sub_val){
$result[$i][$key]=$sub_val;
$i++;
}
$i=0;
}
