How to unfollow some friend who sign up my app twitter - php

Question

I want to follow/unfollow some friends who authorize my Twitter app.
For example:
User signs in with my twitter application and he wants to follow some people
How does it work? I wrote some code here but not working, The session works fine, The user signs in but create/friendship not working, why?
<?php
session_start();
require_once('TwitterAPIExchange.php');
require_once('tmhOAuth.php');
require_once('tmhUtilities.php');
require_once('twitteroauth.php');
require 'twconfig.php';
echo $_SESSION['oauth_token'];
echo "<br />";
echo $_SESSION['oauth_token_secret'];
$twitteroauth = new TwitterOAuth($consumerKey, $consumerKeySecret, $_SESSION['oauth_token'], $_SESSION['oauth_token_secret'] );
$twitteroauth->post('friendships/create', array('screen_name' => 'savanpaun'));
?>
Simply put, I want people follow/unfollow friends using signup in my application directly.

Answer 1

here is a sample code to follow someone.I’ve had used Abraham library you can get it from here
https://github.com/abraham/twitteroauth.
also this is a twitter documentation you can check it out
https://dev.twitter.com/rest/reference/post/friendships/create. and to unfollow someone just use 'friendships/destroy'
<?php
echo "<pre>";
$consumerKey = 'your consumer key';
$consumerSecret = 'your consumer secret key';
$oAuthToken = 'your oauth token';
$oAuthSecret = 'your oauth secret';
require_once('twitteroauth.php');
$tweet = new TwitterOAuth($consumerKey, $consumerSecret, $oAuthToken, $oAuthSecret);
//get friend list
$list= $tweet->post('friendships/create', array('screen_name' => 'archish9'));
var_dump(json_decode($list));
print_r($list);
?>

Answer 2

I copy paste you example and replace in the last line with destroy command
<?php
session_start();
require_once('TwitterAPIExchange.php');
require_once('tmhOAuth.php');
require_once('tmhUtilities.php');
require_once('twitteroauth.php');
require 'twconfig.php';
echo $_SESSION['oauth_token'];
echo "<br />";
echo $_SESSION['oauth_token_secret'];
$twitteroauth = new TwitterOAuth($consumerKey, $consumerKeySecret, $_SESSION['oauth_token'], $_SESSION['oauth_token_secret'] );
$twitteroauth->post('friendships/destroy', array('user_id' => 'iduser'));
?>
this line
$twitteroauth->post('friendships/destroy', array('user_id' => 'iduser'));
I hope that this help you in some way
