Upload banners to youtube via PHP - php

Question

I am new to youtube API
I am trying to upload the banners to youtube video using Google's provided source code and API and getting this error
An client error occurred: Error calling PUT https://www.googleapis.com/upload/youtube/v3/channelBanners/insert?uploadType=resumable&upload_id=AEnB2Uopf1XKEFaoQx4Gkfu8tZizSmvAX1l4JWPJ7txZcvQYCvo8-pfJVgJU-WiIsQI4mL8pkZwdjeUoKYvLVpSMmLI6ulN1uQ: (400) Invalid Upload Request
EDIT
<?php
/**
* This sample sets a custom banner for a user's channel by:
*
* 1. Uploading a banner image with "youtube.channelBanners.insert" method via resumable upload
* 2. Getting user's channel object with "youtube.channels.list" method and "mine" parameter
* 3. Updating channel's banner external URL with "youtube.channels.update" method
