Try json_encode(). JSON is the first, best, and only answer for php<->javascript data transfers.

That's core/basic javascript, and work exactly the same as in PHP. You know how to do it in PHP, so you know how to do it in JS.

<script>var cities = <?php echo json_encode($cities); ?>;</script>

then to access the data

<script>
  cities['San Mateo']['Air'][0]; // 4
  cities['San Mateo']['Air'][1]; // 3-5 Working Days
  // etc

  // looping
  for( var key in cities) {
    // key = city name
  }
</script>

You can use json_encode to convert the array to JSON:

echo json_encode($cities);
exit;

PHP

echo json_encode($cities);

jQuery

$.getJSON("php_file.php",function(data) {
    // "data" is the echoed encoded array from the php file.

    // "array"."city name"."'air' or 'sea'"."number value that is in the PHP file"
    data.Caracas.air.4 // this is how you access the data inside the array
});
