Api Call Var_Dump To Php Variable Help


Recommended Posts


function mtgox_query($path, array $req = array()) {
// API settings
$key = '7583cda31885';
$secret = '';

// generate a nonce as microtime, with as-string handling to avoid problems with 32bits systems
$mt = explode(' ', microtime());
$req['nonce'] = $mt[1].substr($mt[0], 2, 6);

// generate the POST data string
$post_data = http_build_query($req, '', '&');

// generate the extra headers
$headers = array(
 'Rest-Key: '.$key,
 'Rest-Sign: '.base64_encode(hash_hmac('sha512', $post_data, base64_decode($secret), true)),

// our curl handle (initialize if required)
static $ch = null;
if (is_null($ch)) {
 $ch = curl_init();
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
 curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MtGox PHP client; '.php_uname('s').'; PHP/'.phpversion().')');
curl_setopt($ch, CURLOPT_URL, 'https://mtgox.com/api/'.$path);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

// run the query
$res = curl_exec($ch);
if ($res === false) throw new Exception('Could not get reply: '.curl_error($ch));
$dec = json_decode($res, true);
if (!$dec) throw new Exception('Invalid data received, please make sure connection is working and requested API exists');
return $dec;

// example 1: get infos about the account, plus the list of rights we have access to

// old api (get funds)

// trade example
// var_dump(mtgox_query('0/buyBTC.php', array('amount' => 1, 'price' => 15)));\


OutPut :

array(2) { ["usds"]=> string(8) "37.94073" ["btcs"]=> string(10) "6.44987703" }
