Array ( [0] => 33160,         [1] => 33280,         [2] => 33180,         [3] => 33163,         [4] => 33181,         [5] => 33164,         [6] => 33162,         [7] => 33179,         [8] => 33154,         [9] => 33008,         [10] => 33009,         [11] => 33161,         [12] => 33261,         [13] => 33269,         [14] => 33169,         [15] => 33022,         [16] => 33141,         [17] => 33168,         [18] => 33020,         [19] => 33023,         [20] => 33019,         [21] => 33153,         [22] => 33238,         [23] => 33138,         [24] => 33167,         [25] => 33082,)  

Answer 1

I would turn it into CSV form, like so:

$string_version = implode(',', $original_array) 

You can turn it back by doing:

$destination_array = explode(',', $string_version) 

Answer 2

I would turn it into a json object, with the added benefit of keeping the keys if you are using an associative array:

 $stringRepresentation= json_encode($arr);
