Put request using curl - php

Question

after I succeeded in making a POST request and grab the values in the web service i'm building. I'm facing a problem regarding the Put Request. I managed to make the Put Request and I sent an array containing name and id for the update purpose this way:
curl_setopt($ic, CURLOPT_POSTFIELDS, http_build_query($data));
But when I try to grab the id sent using $_POST['id'] I get the undefined index error, I printed_r($_POST) and it's empty. Now I dont't believe there is a super global array for PUT like for POST and even if it exists , I don't think there is :
curl_setopt($ic, CURLOPT_PUTFIELDS, http_build_query($data));
in curl have you even been through a similar error? any idea?
To take a look at my previous post concerning the post request to have a better understanding of what I'm trying to do , it's here

Answer 1

Try this
curl_setopt($ic, CURLOPT_PUTFIELDS, json_encode($data));
and take it by
$array_get = json_decode(file_get_contents('php://input'));

Answer 2

use this CURLOPT_CUSTOMREQUEST =PUT and then just set values with CURLOPT_POSTFIELDS
or
you can use custom header CURLOPT_HTTPHEADER
eg.
curl_setopt($ch, CURLOPT_HTTPHEADER, array('X-HTTP-Method-Override: PUT'));
The script below demonstrates how you make a PUT request.
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "url");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT"); // note the PUT here
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Content-Length: ' . strlen($data_string)
));
// execute the request
$output = curl_exec($ch);
// close curl resource to free up system resources
curl_close($ch);

Answer 3

The $_POST only for method=post;
You use method=put, so the $_POST is empty.
You can get the putdata like this:
$_PUT = array();
if('PUT' == $_SERVER['REQUEST_METHOD']){
parse_str(file_get_contents('php://input'), $_PUT);
}

Answer 4

This is the secret to sending a PUT request:
curl_setopt($ch, CURLOPT_POST, true); // <-- NOTE this is POST
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT"); // <-- NOTE this is PUT
A full example:
$vals = array("email" => "hi#example.com", "phone" => "12345");
$jsonData = json_encode($vals);
curl_setopt($ch, CURLOPT_POST, true); // <-- NOTE this
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT"); // <-- NOTE this
//We want the result / output returned.
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type:application/json',
'Content-Length:' . strlen($jsonData),
'X-Apikey:Any_other_header_value_goes_here'
));
//Our fields.
curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonData);
//Execute the request.
$response = curl_exec($ch);
echo $response;
