Nested loop only returns data from the last iteration [duplicate]

Question

Can someone explain to me why this isn't working? I'm trying to push an array into another array, but its only coming back with the last item from the $votes array.

foreach($json['area'] as $row) {
    $name = $row['name'];
    $group = $row['array']['group'];
    $majority = $row['array']['majority'];
    $candidates = $row['array']['candidates'];
    foreach ($candidates as $candidate) {
        $vote = $candidate["votes"];
        $candi = $candidate["name"];
        $votes = array("vote" => $vote, "candidate" => $candi);
    }
    $array = array("name" => $name, "group" => $group, "majority" => $majority, "votes" => $votes);

    $results[] = $array;
}

Each iteration of the outer loop is only producing a single $votes array , seemingly for a single candidate, in this line:

$votes = array("vote" => $vote, "candidate" => $candi);

If you want to capture multiple entries in that array for each row, you need to make it a multi-dimensional array also:

$candidates = $row['array']['candidates'];
$votes = [];
foreach ($candidates as $candidate) {
    $votes[] = array(
        "vote"      => $candidate["votes"], 
        "candidate" => $candidate["name"]
    );
}

$array = array(
    "name"     => $name, 
    "group"    => $group, 
    "majority" => $majority, 
    "votes"    => $votes
);
