在For循环中将PHP变量存储到JavaScript变量中

I know how to pass a PHP variable into JavaScript variable one by one, but now I wish to pass a bunch of variable in a For loop and I just stuck.

<?php
        $m = new MongoClient();
        $db = $m->data_from_tweeter;
        $collection = $db->output;
        $cursor = $collection->find();
        foreach($cursor as $document){
            echo $document['place'] ;
            echo $document['fir'];
            echo $document['sec'];
        }
?>

I want to store 'place' as a String variable, 'fir' and 'sec' as two Num variables, and make them look like:

var num_1 {
    some_place : some_fir,
    some_place : some_fir,
    some_place : some_fir,
    ....
}

and

var num_2 {
    some_place : some_sec,
    some_place : some_sec,
    some_place : some_sec,
    ....
}

How can I make it? Thanks in advance!

    The following code snippet might help get you started:

    $num_1 = "var num_1 = {
    ";
    $num_2 = "var num_2 = {
    ";
    foreach ($cursor as $document) {
            $num_1 .= "    {$document['place']} : {$document['fir']},
    ";
            $num_2 .= "    {$document['place']} : {$document['sec']},
    ";
    }  
    $num_1 .= "};
    ";
    $num_2 .= "};
    ";
    
    echo $num_1;
    echo $num_2;
