I don't know if this is what u are asking for but an easy way of storing/getting array from a database is just storing your array as a string separated by a character like "," or ";"(of course make sure you don't use it in your string) like:

// code to upload array as string
$array = array("1","2","3");
$arraytostring = '';
$arraycounter = 1; // counter for check the last element
foreach($array as $element){
   $arraytostring .= $element;
   if($arraycounter != count($array)){ // don't print the char if this is the last
      $arraytostring .= ",";
   }
}
// now $arraytostring is your array as a text then you can upload with your db script
// the code to easily retrieve the array

$array = explode(',',$row['column']);
