php - Edit json response from curl response -

<?php $json_url = "http://openexchangerates.org/api/latest.json?app_id=xxxxx&callback=angular.callbacks._0";  $curl = curl_init(); curl_setopt($curl, curlopt_url, $json_url); curl_setopt($curl, curlopt_header, false); curl_setopt($curl, curlopt_returntransfer, 1); curl_setopt($curl, curlopt_http_version, curl_http_version_1_1); $response = curl_exec($curl);  $jsonstring = json_encode($response, true); $data=json_decode($jsonstring);  echo '<pre>',print_r($data),'</pre>';  $status = curl_getinfo($curl); curl_close($curl); 

the output is:

angular.callbacks._0({     "disclaimer": "xx",     "license": "xx",     "timestamp": 1368136869,     "base": "usd",     "rates": {         "aed": 3.672819,         "afn": 53.209,         "all": 107.953875,         "aoa": 96.358934,         "ars": 5.214887,          ....         "xof": 501.659003,         "xpf": 91.114876,         "zmk": 5227.108333,         "zmw": 5.314783,         "zwl": 322.387247     } }) 

but need edit output 1 (only 3 rates (aed/afn/aoa)). so, edit json response in section of rates. how can that?

angular.callbacks._0({     "disclaimer": "xx",     "license": "xx",     "timestamp": 1368136869,     "base": "usd",     "rates": {         "aed": 3.672819,         "afn": 53.209,         "aoa": 107.953875,     } }) 

the $response not in correct json format:

you must remove unnecessary parts it:

$jsonstring= substr($response, 21, -1); 

you can do:

<?php $json_url = "http://openexchangerates.org/api/latest.json?app_id=5bf388eb6f7e40209b9418e6be44f04b&callback=angular.callbacks._0";  $curl = curl_init(); curl_setopt($curl, curlopt_url, $json_url); curl_setopt($curl, curlopt_header, false); curl_setopt($curl, curlopt_returntransfer, 1); curl_setopt($curl, curlopt_http_version, curl_http_version_1_1); $response = curl_exec($curl);  $jsonstring= substr($response, 21, -1); $data=json_decode($jsonstring, true);  // list of rates $rates = $data['rates'];  $new_rates = array(); $new_rates['aed'] = $rates['aed']; $new_rates['afn'] = $rates['afn']; $new_rates['aoa'] = $rates['aoa'];  $data['rates'] = $new_rates;  echo 'angular.callbacks._0('.json_encode($data).')';  $status = curl_getinfo($curl); curl_close($curl);
