PHP using CURL inside while loop

Dear Experts,
I connect a server using CURL to send SMS messages.

First, I select the data from my database and send it to the selected numbers.
Then I put it inside a while loop to send it to every number using CURL.

I use below code,

but I wonder which part should I use inside the while loop?
Do I have to initialize CURL for every time?
Which part should I use inside the while loop?

if ($result->num_rows > 0) {

while($row = $result->fetch_assoc()) {
        	
$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => "xxxxxxx",
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "POST",
  CURLOPT_POSTFIELDS => "{\r\n\t\"xxxxx\"\r\n\t}\r\n}",
  CURLOPT_HTTPHEADER => array(
    "accept: application/json",
    "authorization: ".$kullanici_sifre."",
    "content-type: application/json"
  ),
));

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
  echo "cURL Error #:" . $err;
} else {
  echo $response;
}

}
}
