How can I convert that to javascript with every keys same? I want the same array in javascript

Answer 1

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

• LIGHT: How is the values accessible?
• Marc B: exactly the same as any other javascript data structure. arr['Caracas']['air']
• LIGHT: Please do that and show the code to do. Please show me how to access the $cities['Caracas']['air'][0] using javascript and json
• Marc B: 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.

Answer 2

<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>

Answer 3

You can use json_encode to convert the array to JSON:

echo json_encode($cities);
exit;

• LIGHT: Please do that and show the code to do. Please show me how to access the $cities['Caracas']['air'][0] using javascript and json

Answer 4

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
});
