thank help!

// create new curl resource $ch = curl_init();  // set url , other appropriate options      $defaults = array(     curlopt_url => 'https://api-fxpractice.oanda.com/v1/accounts/6531071/orders',     curlopt_post => true,     curlopt_postfields => "instrument=eur_usd&units=1000&side=buy&type=market");     curl_setopt_array($ch, $defaults);  // grab url , pass browser    $exec =  curl_exec($ch);     // close curl resource, , free system resources curl_close($ch);  if ($exec) {     print_r($exec); //print results }  

and answer question:

curl -x post implies http post request, -d parameter (long version: --data) tells curl follows post parameters
