Q: PHP sending POST request via curl I need to make a POST request to an external http API using curl. When I call the API using the curl command line, it returns the correct data. However, I'm struggling to get the right data when calling it from a php script.
When I use the curl command from the terminal, I get the correct data: 
curl -i -H "Accept: application/json" -X POST -d "type_category_id=4" http://example.com/api/
What is the correct format for the CURLOPT_POSTFIELDS in my curl_setopts() in php?
I tried the following (and failed):
<?php
$data = "type_category_id=4";

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

$result = curl_exec($ch);
?>


A: Make it Accept: application/json instead of Content-Type: application/json
You have done that in the command line but not in the php script.
