    Don't store multiple values in a single database field. If you have a table of (num, value) and 4 rows this becomes significantly easier. – danblack Oct 23 '20 at 05:16

This can be a way to resolve

$a = "1=>4,2=>5,3=>3,4=>1";
$a = "{" . preg_replace("/(\d+)=>/", '"${1}":', $a) . "}";
$output = json_decode($a, true);

// output
Array
(
    [1] => 4
    [2] => 5
    [3] => 3
    [4] => 1
)

  • First explode them using , .
  • Then loop through them to assign it to array after exploding by =>.
$a = '1=>4,2=>5,3=>3,4=>1';
$final = [];
foreach(explode(',', $a) as $value){
  list($key, $val) = explode('=>', $value);
  $final[$key] = $val;
  
}

echo '<pre>'; print_r($final);
Output:

Array
(
    [1] => 4
    [2] => 5
    [3] => 3
    [4] => 1
)
