以逗號分開的值，用curl and json傳送給http

Question

假設欄位值 2018/04/16, 2018/04/17, 2018/04/18, 2018/04/19, 2018/04/20, 2018/04/21, 2018/04/28 當我另一面處理的時候如何轉換成 array 並且丟json給指定的http? 利用curl $data = array( "date" => $date ); $data_string = json_encode($data); $ch = curl_init($api_signin); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST"); curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json')); $result = curl_exec($ch); curl_close($ch); $date這邊怎麼寫才對啊？

Answer 1

$data = array('2018/04/16','2018/04/17','2018/04/18','2018/04/19','2018/04/20','2018/04/21','2018/04/28');
