How to send array of complex objects to another page in PHP? - php

Question

I have an array $batchRequest that looks like this:

So its an array whose elements are complex objects. I need to send them to another page called parallelImport.php. Here is what I've tried:
Using JSON
$data = array('batchArrayChild' => json_encode($batchRequest), 'app_id' => $appId, 'app_secret' => $appSecret);
$endpoint_url = 'https://some-domain.net/pages/parallelImport.php';
$curl = curl_init($endpoint_url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);
$curl_response = curl_exec($curl);
$result = $curl_response;
print_r($result);
As you can see I json_encodeed $batchRequest and send it via cURL, and here is what it outputs:
string(16) "[[],{},{},{},{}]"
Using http_build_query
$data = array('batchArrayChild' => http_build_query($batchRequest), 'app_id' => $appId, 'app_secret' => $appSecret);
$endpoint_url = 'https://some-domain.net/pages/parallelImport.php';
$curl = curl_init($endpoint_url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);
$curl_response = curl_exec($curl);
$result = $curl_response;
print_r($result);
And after I do var_dump($_POST['batchArrayChild']) on parallelImport.php it says:
string(0) ""
Do you know any other way in which I could send this array to execution script and to get some kind of response?

I don't like sending complex (internal) objects between systems, so I would have created a DTO (data transfer object) with public properties and used that object to send the data to avoid any coupling of objects between services. The DTO could even be of type stdClass if you want to make it simple.
If you want to make the services super dependent to each other including sharing state you could try to use serialize() on the data
