Make a new multi dimensional array from the existing array in smarty - smarty

Question

My whole moto in this question is to make a new array from existing array and to reverse the first and second index of array.
I have an array
Array
(
[0] => Array
(
[0] => Array
(
[field] => Array
(
[name] => name
[tabindex] => 0
)
[colspan] => 3
)
)
[1] => Array
(
[0] => Array
(
[field] => Array
(
[name] => sequence
[tabindex] => 0
)
[colspan] => 3
)
)
[2] => Array
(
[0] => Array
(
[field] => Array
(
[name] => description
[tabindex] => 0
)
[colspan] => 3
)
)
[3] => Array
(
[0] => Array
(
[field] => Array
(
[name] => status
[tabindex] => 0
)
[colspan] => 3
)
)
[4] => Array
(
[0] => Array
(
[field] => Array
(
[name] => modified_by_name
[customCode] => {$fields.date_modified.value} {$APP.LBL_BY} {$fields.modified_by_name.value}
[label] => LBL_DATE_MODIFIED
[tabindex] => 0
)
[colspan] => 3
)
)
[5] => Array
(
[0] => Array
(
[field] => Array
(
[name] => created_by_name
[customCode] => {$fields.date_entered.value} {$APP.LBL_BY} {$fields.created_by_name.value}
[label] => LBL_DATE_ENTERED
[tabindex] => 0
)
[colspan] => 3
)
)
[6] => Array
(
[0] => Array
(
[field] => Array
(
[name] =>
)
)
[1] => Array
(
[field] => Array
(
[name] =>
)
)
)
)
Now i have to make a new array with first index on second and second on first index like this But have to do only in smarty not in php etc
Array
(
[0] => Array
(
[0] => Array
(
[field] => Array
(
[name] => name
[tabindex] => 0
)
[colspan] => 3
)
[1] => Array
(
[field] => Array
(
[name] => sequence
[tabindex] => 0
)
[colspan] => 3
)
[2] => Array
(
[field] => Array
(
[name] => description
[tabindex] => 0
)
[colspan] => 3
)
[3] => Array
(
[field] => Array
(
[name] => status
[tabindex] => 0
)
[colspan] => 3
)
[4] => Array
(
[field] => Array
(
[name] => modified_by_name
[customCode] => {$fields.date_modified.value} {$APP.LBL_BY} {$fields.modified_by_name.value}
[label] => LBL_DATE_MODIFIED
[tabindex] => 0
)
[colspan] => 3
)
[5] => Array
(
[field] => Array
(
[name] => created_by_name
[customCode] => {$fields.date_entered.value} {$APP.LBL_BY} {$fields.created_by_name.value}
[label] => LBL_DATE_ENTERED
[tabindex] => 0
)
[colspan] => 3
)
)
)

I think the following might help you.
You could loop the array you have and fill a new array with the values. Lets call the original $firstArray and the new one $newArray. I see that the first item from the subarrays are what you need(and there are no other items apart from 0) so you could do the following:
{$newArray = []}
{foreach $firstArray as $item}
{$newArray[] = $item.0}
{/foreach}
$item.0 selects the first subarray(there are no other). You might have to use $item[0] depending on your smarty version.
If there is more than 1 subarray, then loop $items first before you add an array to the $newArray.
It looks as if there's another array encapsuling your firstArray, so perhaps you need to select the subarray from the main one first....
note: I used smarty 3. Perhaps you use a different version, be sure to check the syntax for your version.
