Here is an example how to generate YouTube video browser-based uploading form by PHP:

<?php
$youtube_email = "example@youtube.com"; // Change this to your youtube sign in email.
$youtube_password = "password"; // Change this to your youtube sign in password.

$postdata = "Email=".$youtube_email."&Passwd=".$youtube_password."&service=youtube&source=Example";
$curl = curl_init("https://www.google.com/youtube/accounts/ClientLogin");
curl_setopt($curl, CURLOPT_HEADER, "Content-Type:application/x-www-form-urlencoded");
curl_setopt($curl, CURLOPT_POST, 1);

curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 1);
$response = curl_exec($curl);
curl_close($curl);

list($auth, $youtubeuser) = explode("\n", $response);
list($authlabel, $authvalue) = array_map("trim", explode("=", $auth));
list($youtubeuserlabel, $youtubeuservalue) = array_map("trim", explode("=", $youtubeuser));

$youtube_video_title = "Example"; // This is the uploading video title.
