无法从php输入数组到javascript

Question

I have this code:

<?php $result = array();
while ($row = $stmt->fetch(PDO::FETCH_ASSOC)){
$result[] = sprintf("{lat: %s, lng: %s}",$row['lat'],$row['lng']);} ?>

<?php $resultAM = join(', ',$result);
echo $resultAM; ?>

the $resultAM represents this result (anyway I'm using SQL):

{lat: -7.0476101, lng: 112.7323577}, {lat: -7.0319093, lng: 112.7614287}, {lat: -7.0433001, lng: 112.7606889}, {lat: -7.0459718, lng: 112.7583679}

I'm going to put the code in javascript with this code:

var distanceM = [<?php echo json_encode($resultAM); ?>];

but the result wont appear.

Anyone can help me? I'm new at PHP. Thanks!

PHP 2D Array can simply transform into JS Array of objects. For example, we have a php array:

$arr = array('city1' => array('TBILISI' => 'Georgia'), 'city2' => array('LONDON' => 'UK'));

In JS we can simply write:

let myArr = <?php echo json_encode($arr); ?>;
console.log(myArr); // Console it..

it now looks in JS like that:

{"city1":
       {"TBILISI": "Georgia"},
"city2": 
       {"LONDON": "UK"}
}
