Hello,
This is a little out of topic, but here are few hints:
The easiest way to do that is to build a PHP array, and to use
JSON_Encode to convert it into a JSON encoded string;
You also need to change the content-type of your response to let
prototype know it is actually JSON.
Simple example:
<?php
$myCities = Array("Paris","Madrid","New-York","London");
header('Content-Type: application/json');
print json_encode($myCities);
?>
