Answer 1

$str = "[1=>2,3,4][5=>6,7,8][9=>10,11,12][13=>14,15][16=>17,18]";
$str = explode("]", $str);
$finalResult = array();

foreach ($str as $element) {
    if (!empty($element)) {
        $element = substr($element, 1);
        $element = explode("=>", $element);

        // element[0] contains the key
        $element[1] = explode(",", $element[1]);
        $finalResult[$element[0]] = $element[1];
    }
}

print_r($finalResult);
