PHP array to javascript array

Question

Suppose, I have this array in php

$cities=array(
    \"Caracas\"=>array(
        \"air\"=>array(
            \"4\",\"3-5 Working Days\",\"Saturday\"
               


        

Answer 1

You can use json_encode to convert the array to JSON:

echo json_encode($cities);
exit;

Answer 2

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
});

Answer 3

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

Answer 4

<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>
