php - push array into array - key issue

Question

i am trying to push multiple arrays into 1 big array, resulting in a 2 lvl array.

I got this set of arrays for example:

Array
(
    [cod] => ffffd
    [denum] =         


        

Answer 1

first convert your array too JSON

while($query->fetch()){
   $col[] = json_encode($row,JSON_UNESCAPED_UNICODE);
}

then vonvert back it to array

foreach($col as &$array){
   $array = json_decode($array,true);
}

good luck
