Answer 1

This will do the work
function restructure($arr){
$newArr = array();
foreach($arr as $k => $v){
foreach($v as $k1 => $v1){
foreach($v1 as $k2 => $v2){
$newArr[$k][$k2][$k1] = $v2;
}
}
}
return $newArr;
}

As SiGanteng suggested, i dont see other ways than a for/foreach loop:
function buildArray($source, $key = false)
{
// Build the new array
$new_array = array();
// Define groups
$groups = $key === false ? array_keys($source) : array($key);
foreach($groups AS $group)
{
// Get the keys
$keys = array_keys($array[$group]);
// Count the values
$num_entries = count($array[$group][$keys[0]]);
for($i = 0; $i < $num_entries; $i++)
{
foreach($keys AS $key)
{
$new_array[$group][$i][$key] = $array[$group][$key][$i];
}
}
}
return $new_array;
}
This allow you to define the key you need to build; If not specified, the function build the array for every key.

This should work.
function formatit($arr) {
$new = array();
foreach($arr as $k=>$v) {
foreach($v as $k1=>$v1) {
$new[$k1][$k] = $v1;
}
}
return $new;
}
Tested. Call it as
$arr['text'] = formatit($arr['text']);
