Assuming your three arrays are called $array1
, $array2
, and $array3
here's a loop that will do what you want:
foreach(array($array1, $array2, $array3) AS $array) {
foreach($array AS $key => $value) {
foreach($value AS $subkey => $subvalue) {
$final[$key][$subkey] = $subvalue;
}
}
}

If you have an unknown number of input arrays to merge, it would be trivial to turn this into a function to handle that.
