Sending POST via curl to the server doesn't work - php

Question

I am trying to send a POST request to the server (JBOSS) which is running on localhost:9090 as shown below but it doesn't seem to be working. I mean, I am not seeing my webservice getting executed. Am I doing everything right below?
Since $_POST["mydata"] contains the following :
[{ "name": "FirstName", "value": "Mickey" }, { "name": "LastName", "value": "Mouse" }]
which is the result of running JSON.stringify() on the javascript object (using serializeArray()), I am not sending application/json related thing in the header.
$urlTest = 'http://localhost:9090/JAXRS_POST_Request/rest/Request/insertDataToDB';
$rCURL = curl_init();
curl_setopt($rCURL, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($rCURL, CURLOPT_POSTFIELDS, $_POST["myData"]);
curl_setopt($rCURL, CURLOPT_URL, $urlTest);
curl_setopt($rCURL, CURLOPT_HEADER, 0);
curl_setopt($rCURL, CURLOPT_RETURNTRANSFER, 1);
$response_post = curl_exec($rCURL);
curl_close($rCURL);
But if I have to manually test the webservice using a client like POSTMAN, I have to specify under headers as Content-Type : application/json and send it like this through the Body and it works perfectly fine there :
But while sending the request via curl, since JSON.stringify() converts the javascript object to string to send it to the server, I am confused whether I need to use header thing in my POST request or not.
P.S. A simple curl based GET request has worked fine for me so my application is successfully contacting the server.

Try this:
$urlTest = 'http://localhost:9090/JAXRS_POST_Request/rest/Request/insertDataToDB';
$data = 'FirstName=Mickey&LastName=Mouse';
$rCURL = curl_init();
curl_setopt($rCurl, CURLOPT_POST, true);//
curl_setopt($rCURL, CURLOPT_POSTFIELDS, $data);
curl_setopt($rCURL, CURLOPT_URL, $urlTest);
curl_setopt($rCURL, CURLOPT_HEADER, 0);
curl_setopt($rCurl, CURLOPT_RETURNTRANSFER, true);
if(curl_exec($rCurl) === false){
echo 'Curl error: ' . curl_error($rCurl);
}else{
$response_post = curl_exec($rCURL);
}
curl_close($rCurl);
