output must be

Array
(
    [6] => 1
    [4] => 2

[Lander]

$arr = explode(';', $string);
$output = [];
foreach ($arr as $item) {
    list($key, $value) = explode('=', $item);
    $output[$key] = $value;
}
var_dump($output);

upd: или так

$output = [];
array_map(function($item) use (&$output) {
    list($key, $value) = explode('=', $item);
    $output[$key] = $value;    
}, explode(';', $string));
