I am creating a simple rest API using Codeigniter where API works fine. Now, the problem is that when I am getting data from eventapi using curl it shows me output i.e array(0) { } I don't know why? So, How can I solve this issue? Please help me.
Thank You

If the above one is your code, you didn't add any parameters. The array passing with empty input. So you get empty output. Please correct the input.
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,
$inputParameters");
Please add these lines along with the curl .
And don't forget to add the header also .
//set the content type to application/json
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));
//return response instead of outputting
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
