PHP : generate a token using a Post method - php

Question

Good day,
Before getting back on Stackoverflow, I have been googling the entire afternoon without being really successful.
What I am trying to do is to get a token from myfox api by referring to their doc which says
A fresh token must be generated to be able to perform API calls. The
token can be requested by calling the following method
https://api.myfox.me/oauth2/token and providing the parameters below
(through POST): client_id, client_secret, username, password and
grant_type set to password.
Hence my code :
function getToken()
{
$clientID = "a65000ee0c57f2e37260e90c375c3";
$clientSecret = "MyLongSecretCode";
$exportFile = "myfile.txt";
$userName = "somebody#somewhere.com";
$userPass = "myPassword123";
$sourceWebsite = "https://api.myfox.me/oauth2/token?client_id=" . $clientID . "&client_secret=" . $clientSecret . "&username=" . $userName . "&password=" . $userPass . "&grant_type=password";
file_put_contents($exportFile, fopen($sourceWebsite , 'r'));
}
All I'm getting is a PHP error which says that the method is not allowed.
Any idea what I am missing here?
Many thanks for your kind help on this subject.
Edit 17.03.2017 :
I have been told by other users that I might be able to achieve this by using curl and it looks like, again, by reading the documentation that this is something that I can do :
A fresh token must be generated to be able to perform API calls. The
token can be requested by calling the following method
https://api.myfox.me/oauth2/token and providing the parameters below
(through POST): client_id, client_secret, username, password and
grant_type set to password. curl -u CLIENT_ID:CLIENT_SECRET
https://api.myfox.me/oauth2/token -d
'grant_type=password&username=YOUR_USERNAME&password=YOUR_PASSWORD'
or curl https://api.myfox.me/oauth2/token -d
'grant_type=password&client_id=CLIENT_ID&client_secret=CLIENT_SECRET&username=YOUR_USERNAME&password=YOUR_PASSWORD'
Now, for my question : is there a way to translate this curl -u query into a php instruction and to output the contents to a file out of it that would look like :
{"access_token":"********************************","expires_in":3600,"token_type":"Bearer","scope":null,"refresh_token":"********************************"}
Thanks again for your help.

Thanks all a lot for your hints, here is a script that is working :
I hope that this script (and this post) can at some point be helpful to someone else. I wish you a very nice week-end.
<?php
$clientID = 'b85036758c385c3cd0c57f2e37260f91';
$clientSecret = 'MyLongSecretCode';
$username = 'myemailaddress#provider.net';
$passwd = 'mypassword';
// Get cURL resource
$curl = curl_init();
// Set some options - we are passing in a useragent too here
curl_setopt_array($curl, array(
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_URL => 'https://api.myfox.me/oauth2/token',
CURLOPT_USERAGENT => 'Codular Sample cURL Request',
CURLOPT_POST => 1,
CURLOPT_POSTFIELDS => array(
'grant_type' => 'password',
'client_id' => $clientID,
'client_secret' => $clientSecret,
'username' => $username,
'password' => $passwd
)
));
// Send the request & save response to $resp
$resp = curl_exec($curl);
echo $resp;
// Close request to clear up some resources
curl_close($curl);
?>
