php - Converting json to jsonp -

i created account on 500px.com, , use api: http://developer.500px.com/

but looks cant return jsonp, json.

is there way make php file can post url -> make convert response api json jsonp, can handle on client side?

i havent been writing php in long time, appreciated. hope idea, otherwise ill elaborate. thanks

sure can. difference between json , jsonp jsonp wrapped function name;

{ "x": "hello" } // json foo({ "x": "hello" }); // jsonp. 

in it's simplest form can end this;

<?php echo $_get['callback']; ?>(<?php echo file_get_contents($_get['endpoint']); ?>); 

and you'd expect clients use this;

http://yourserver.com/proxy.php?endpoint=https%3a%2f%2fapi.500px.com%2fv1%2foauth%2fauthorize&callback=foo 

note encoded url , addition of callback parameter know function invoke.

of course, you'll need valid input; check existance of parameters, check endpoint passed isn't malicious etc. might want cache responses on server stop reaching limits imposed on api.

something more resilient against malicious input like;

// checks existence, , checks input isn't array function getasstring($param) {     if (is_null($_get[$param]) || !is_string($_get[$param])) {         return '';     }      return $_get[$param]; }  $endpoint = getasstring('endpoint'); // check callback alpha-numeric characters $callback = preg_replace('/[^\w\d]/', '', getasstring('callback')); // check endpoint 500px api $is_api = (strpos($endpoint, 'https://api.500px.com') === 0);  if (strlen($callback) > 0 && $is_api) {     echo $callback . '(' . file_get_contents($endpoint) . ')' } else {     // handle error }
