What is the most efficient way to combine & extract an array of about 20 separate digits (all 0-9) in a single mysql field (e.g. 1,2,1,0,5 as 12105)?

$arr1 = array(0, 1, 2, 3, 4, 5);

$a = implode("", $arr1);
$b = implode(",", $arr1);

$a is now '012345'
$b is now '0,1,2,3,4,5'

$arr2 = explode(",", $b);

$arr2 is now = $arr1
