试试json_encode()。JSON 是 php<->javascript 数据传输的第一个、最好的和唯一的答案。

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

然后访问数据

<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>

您可以使用json_encode将数组转换为 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
});
