如何在php数组json 中使用curl发送post数据

像数组一样发布curl参数排序列表这是我的代码

<?php
class PostOrderPolicy extends CI_Controller{
public function index(){
$data = $this->getData();
foreach ($data as $key) {
$orderListt = array(
'orderDate' => $key['order_date'],
'IDNumber' => $key['IDnumber'],
'itemDescription' => $key['description']
);
$send = $this->sendData($orderListt, $key['resi_number']);
if ($send) {
$res["message"] = "Sukses";
}else{
$res["message"] = "Gagal";
}
}

//echo json_encode($res);
}
private function getData(){
$sql = "SELECT * FROM t_transaction WHERE status='00'";
return $this->db->query($sql)->result_array();
}
private function sendData($data){
$result = array();
$url = "https://contoh.co.id/createPolicy";
$res    = array();
$sign   = $this->getSign();
$upperSign = strtoupper($sign);
//$random = $this->getRandomStr();
$random = '049KN1PSOL16QHIF';
$batch  = 'BATCH000002';
$dataArr = array(
'sign' => $upperSign,
'randomStr' => $random,
'batchNo' => $batch,
'orderList' => [$data]
);
$string     = json_encode($dataArr);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST"); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, $string);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));
$response = json_decode(curl_exec($ch), TRUE);
print_r($response);
print_r($string);
}
}
?>

但是我的结果发布字段[在此输入图像描述][1][1] ：https://i.stack.imgur.com/b7LEP.png

我想要这样[在此输入图像描述][2][2] ：https://i.stack.imgur.com/xExJ2.png

{"sign":"35EAF78F95A52DDA79FC9911559026F6","randomStr":"049KN1PSOL16QHIF","batchNo":"BATCH000002","orderList":[{"orderDate":"2020-07-01 11:00:00.000","resiNumber":"99875646957","itemDescription":"testing"},{"orderDate":"2020-07-01 ]11:00:00.000","IDNumber":"28929740170","itemDescription":"testing"}]}

返回响应而不是输出：

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

执行POST请求：

$result = curl_exec($ch);

关闭cURL资源：

curl_close($ch);
