PHP等效于以下CURL代码

Question

I have a strange problem with PHP Curl. I want to set post fields option multiple times. What is the equivalent PHP code for the following CURL code:

curl -X POST https://example.com \
 -d 'contacts=my_list' \
 -d 'data[]={"email":"[e-mail]","name":"contactName1"}' \
 -d 'data[]={"email":"[e-mail]","name":"contactName2"}'

I want to send data[] as multiples of CURLOPT_POSTFIELDS. I already tried setting post field as

$post = "?contacts=my_list&data[]=%7B%22email%22%3A%22address1%40domain.com%22%2C%22name%22%3A%22contactName1%22%7D&data[]=%7B%22email%22%3A%22address2%40domain.com%22%2C%22name%22%3A%22contactName2%22%7D"

Can we have curl set CURLOPT_POSTFIELDS two times like

$post1 = "contacts=my_list&data[]=%7B%22email%22%3A%22address1%40domain.com%22%2C%22name%22%3A%22contactName1%22%7D";
$post2 = "data[]=%7B%22email%22%3A%22address2%40domain.com%22%2C%22name%22%3A%22contactName2%22%7D";
curl_setopt($this->ch, CURLOPT_POSTFIELDS, $post1);
curl_setopt($this->ch, CURLOPT_POSTFIELDS, $post2);
curl_exec($this->ch);

As mentioned in the comments, this is the code you are looking for:

<?php
$post1 = "contacts=my_list&data[]=%7B%22email%22%3A%22address1%40domain.com%22%2C%22name%22%3A%22contactName1%22%7D";
$post2 = "data[]=%7B%22email%22%3A%22address2%40domain.com%22%2C%22name%22%3A%22contactName2%22%7D";
curl_setopt($this->ch, CURLOPT_POSTFIELDS, $post1 . '&' . $post2);
curl_exec($this->ch);
?>

But the best and clearest way to do it is to put all information in arrays and let http_build_query() do the job:

<?php
  $c = curl_init();
  curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($c, CURLOPT_URL, 'http://your_url_here.com');
  curl_setopt($c, CURLOPT_MAXREDIRS, 10);
  curl_setopt($c, CURLOPT_FOLLOWLOCATION, true);
  curl_setopt($c, CURLOPT_SSL_VERIFYPEER, false);

  $postData = array(
   'contacts' => 'my_list',
   'data' => array(
      array('email' => '[e-mail]', 'name' => 'contactName1'),
      array('email' => '[e-mail]', 'name' => 'contactName2'),
   ),
);
  curl_setopt($c, CURLOPT_POSTFIELDS, http_build_query($postData));
  curl_exec($c);
?>
