PHP post to WebAPI - php

Question

Well, I know that the headline look simple, but i was looking from 3 days for an example on how to make the POST request to webapi.
Currently I am using JQuery to do my POST, but I need some php script to run and talk to my C# webAPI, and it seems impossible to find some examples or explain on how to do that.
Someone gave me then Code :
$response = file_get_contents('http://localhost:59040/api/Email/SendEmails');
$response = json_decode($response);
echo ($response);
But this one does nothing - Not even an error on how to go more into the problem.
I simpley need a php script to make the POST request to webapi who gets 1 param(String) and return An ok answer or Error,

Answer 1

After Maalls answer from this post How do I send a POST request with PHP?
The answer was really simple and the code was the following :
$url = 'http://server.com/path';
$data = array('key1' => 'value1', 'key2' => 'value2');
// use key 'http' even if you send the request to https://...
$options = array(
'http' => array(
'header' => "Content-type: application/x-www-form-urlencoded\r\n",
'method' => 'POST',
'content' => http_build_query($data),
),
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
var_dump($result);
Thanks Maalls and dbau for the answer :).
