sorun sadece orada değil. kodu düzenledim atıyorum. çalışmazsa haber verirsin hocam. kolay gelsin.

<?php
 
$ch = curl_init("https://service.payizone.com/token");
$payload = json_encode( array( "app_id"=> 'xxx', "app_secret" => "xxx" ) );
curl_setopt( $ch, CURLOPT_POSTFIELDS, $payload );
curl_setopt( $ch, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
$result = curl_exec($ch);
curl_close($ch);
$result = json_decode($result);
 
$ad=$_POST['name'];
 
$kno=$_POST['number'];
 
$ay=$_POST['month'];
 
$yil=$_POST['year'];
 
$cvv=$_POST['cvv'];
 
$xtut=$_POST['xtut'];
 
 
$payload['card_holder'] = $ad;
 
$payload['card_number'] = $kno;
 
$payload['exp_month'] = $ay;
 
$payload['exp_year'] = $yil;
 
$payload['cvcNumber'] = $cvv;
 
$payload['amount'] = $xtut;
 
$payload['redirect_url'] = "https://xxx.net/";
 
$payload['note'] = "Dijital Ürün";
 
$payload['other_code'] = rand(1, 9999);
 
$ch = curl_init("https://service.payizone.com/pay3D");

$yeni = array(
  'card_holder' => $ad,
   "card_number" => $kno,
   "exp_month" => $ay,
   "exp_year" => $yil,
   "cvv" => $cvv,
   "amount" => $xtut,
   "payment_token" => $resultpayToken,
   "redirect_url" => $redirect,
   "other_code" => $id,
   "note" => $note,
);
$payload = json_encode($yeni);
curl_setopt( $ch, CURLOPT_POSTFIELDS, $payload );
curl_setopt( $ch, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
$result = curl_exec($ch);
curl_close($ch);
$result = json_decode($result);
 
 
 
 
 
 ?>

yaptığım işlem arrayı değişkene atadım. array döngüsünde ise > işareti kullandım.

$yeni = array(
'card_holder' => $ad,
"card_number" => $kno,
"exp_month" => $ay,
"exp_year" => $yil,
"cvv" => $cvv,
"amount" => $xtut,
"payment_token" => $resultpayToken,
"redirect_url" => $redirect,
"other_code" => $id,
"note" => $note,
);
