then simply do a local
Request.JSON({
url: '/proxy.php?url=http://m.airpim.com/json/public/search?&k=&e=1',
onComplete: function(data) {
console.log(data);
}
}).send();
to make it safer, you can just hardwire the url into the proxy and possibly append escaped search terms or whatever so these will become your only argument.
your php script is not retruning any data at the moment. you still need an echo/print ;)
