How to change facebook profile pic using php - php

Question

I want to make a Facebook canvas app for a cause, where I need to change the profile pic of user with his/her permission, I have fetched user's profile pic with selected viewport and placed an overlay of that cause but &makeprofile=1 is not working it redirects me to pic in theater mode. I want something like this app.
<?php
session_start();
require_once __DIR__ . '/Facebook/autoload.php';
$fb = new Facebook\Facebook([
'app_id' => 'app',
'app_secret' => 'secret',

$permissions = ['email','publish_actions']; // optionnal
try {
if (isset($_SESSION['facebook_access_token'])) {
$accessToken = $_SESSION['facebook_access_token'];
} else {
$accessToken = $helper->getAccessToken();
}
} catch(Facebook\Exceptions\FacebookResponseException $e) {
// When Graph returns an error
echo 'Graph returned an error: ' . $e->getMessage();
exit;
} catch(Facebook\Exceptions\FacebookSDKException $e) {
// When validation fails or other local issues
echo 'Facebook SDK returned an error: ' . $e->getMessage();
exit;
}
if (isset($accessToken)) {
if (isset($_SESSION['facebook_access_token'])) {
$fb->setDefaultAccessToken($_SESSION['facebook_access_token']);
} else {
$_SESSION['facebook_access_token'] = (string) $accessToken;
// OAuth 2.0 client handler
$oAuth2Client = $fb->getOAuth2Client();
// Exchanges a short-lived access token for a long-lived one
$longLivedAccessToken = $oAuth2Client->getLongLivedAccessToken($_SESSION['facebook_access_token']);
$_SESSION['facebook_access_token'] = (string) $longLivedAccessToken;
$fb->setDefaultAccessToken($_SESSION['facebook_access_token']);
}
// validating the access token
try {
$request = $fb->get('/me');
} catch(Facebook\Exceptions\FacebookResponseException $e) {

You can´t change the profile picture directly, like it is done in that other App. You MUST redirect the user to the uploaded photo and he can then choose to make it his profile picture on his own. The celebrate pride App is from Facebook.
