Try looking at the following example: POSTing JSON Data With PHP cURL

Useful excerpt:

$data = array("name" => "Hagrid", "age" => "36");                                                                    
$data_string = json_encode($data);                                                                                   

$ch = curl_init('http://api.local/rest/users');                                                                      
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);                                                                  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                      
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
    'Content-Type: application/json',                                                                                
    'Content-Length: ' . strlen($data_string))                                                                       
);                                                                                                                   

$result = curl_exec($ch);

@ammu Why? Which statement does not accept the multidimensional array? json_encode() is the only statement taking the array...

RichardBernards Over a year ago

What is the error you receive from the code supplied?

ammu Over a year ago

if i use this code and $data_string is multidimensional array then response will be NULL

RichardBernards Over a year ago

@ammu Nope... $data_string will be a string with a JSON-representation of a multidimensional array. I don't know who you are sending the request to, but ask them what they would like to receive and post this in the question... Without an error, I cannot help you any further.

The mistake was in checking the response : In Response page: instead of this code...... echo $JSONData = file_get_contents("php://input"); exit(); firstly i used :.............echo json_decode($_POST);exit();

$data_string = json_encode($request);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
    'Content-Type: application/json',                                                                                
    'Content-Length: ' . strlen($data_string))                                                                       
);

$request should be associated array format.
