Retrieve data from PHP within Javascript

Question

I need to convert country codes into their name from Javascript. I found a php array of country codes but I need to pass a javascript variable into the php array to get the country code. Any way to do something like the following? This errors out of course.

function getCountry(code)
 {
 <?php echo $code=?> code;
 return <?php echo $countries[$code] ?>
 }

• user1726343: Output the data structure containing your country codes as JSON, then store it in a variable in JS (the JSON format is native to JS). You can then retrieve values from it as you please.
• adeneo: Why not just convert that array to a valid javascript object, and use the countrycodes as keys to get the names.
• Okan Kocyigit: you can't pass value from javascript to php. it's impossible like this way. you should create an api.
• j08691: Whatever you nitwits do, make sure you give a great answer. user1964129 might be the hottest chick on SO and the last thing we need to do is frighten her off.
• adeneo: @j08691 - +1, I guess I was'nt the only one that noticed that, I just found it a bit inappropriate to comment on it ?

Answer 1

in javascript:

function getCountry(code){
 var countries=<?=json_encode($countries)?>;
 return countries.hasOwnProperty(code)?countries[code]:null;
}

I modified it to use a ternary for the error checking, just shorter code.

• Jonathan Kuhn: @ocanal OP has an array of countries in php and is trying to get that into javascript so they can lookup code in javascript.
• Okan Kocyigit: Ok I got it, that should be like this, not in her way.

Answer 2

function getCountry(code)
 {
 var codes = <?php echo json_encode($codes);?> ;
 return (codes[code] || null);
 }
