Creating a YouTube video downloader using PHP and JavaScript involves a few steps. However, it’s important to note that YouTube’s terms of service prohibit downloading videos without permission. You should only download videos if you have the necessary rights or permissions.
Using PHP
Set up YouTube Data API: First, you need to set up the YouTube Data API and obtain an API key. Follow the instructions provided by Google to enable the API and generate the key.
- Open PowerShell as Administrator: Right-click on the Start menu, and select “Windows PowerShell (Admin)”.
- Enable Execution Policy (if necessary): By default, PowerShell restricts the execution of scripts. You might need to set the execution policy to allow script execution. Run the following command in PowerShell:
Set-ExecutionPolicy Bypass -Scope Process -Force;
iwr https://chocolatey.org/install.ps1 -UseBasicParsing | iex
choco -v
choco install youtube-dl

<?php
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
$videoUrl = $_POST['video_url'];
// Extract video ID from YouTube URL
$videoId = getYouTubeVideoId($videoUrl);
if ($videoId) {
// Download the video
downloadVideo($videoId);
} else {
echo 'Invalid YouTube URL';
}
}
function getYouTubeVideoId($url) {
$videoId = '';
parse_str(parse_url($url, PHP_URL_QUERY), $params);
if (isset($params['v'])) {
$videoId = $params['v'];
}
return $videoId;
}
function downloadVideo($videoId) {
// Use youtube-dl or ffmpeg to download the video
$command = "youtube-dl https://www.youtube.com/watch?v=$videoId";
// Execute the command
exec($command, $output, $returnCode);
if ($returnCode === 0) {
echo 'Video downloaded successfully!';
} else {
echo 'Failed to download video.';
}
}
?>
Install youtube-dl: Ensure that youtube-dl is installed on your server. You can install it via package managers like apt (for Debian-based systems) or brew (for macOS).
Using Javascript
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>YouTube Video Downloader</title> </head> <body> <h2>YouTube Video Downloader</h2> <form id="downloadForm"> <input type="text" id="videoUrl" placeholder="Enter YouTube Video URL"> <button type="submit">Download</button> </form> <div id="message"></div> <script src="script.js"></script> </body> </html>
document.getElementById('downloadForm').addEventListener('submit', function(e) {
e.preventDefault();
var videoUrl = document.getElementById('videoUrl').value;
var videoId = getYouTubeID(videoUrl);
if (videoId) {
downloadVideo(videoId);
} else {
document.getElementById('message').innerText = 'Invalid YouTube URL';
}
});
function getYouTubeID(url) {
// Extract video ID from YouTube URL
// Implementation depends on your specific requirements
}
function downloadVideo(videoId) {
// Send video ID to PHP script for downloading
// You can use AJAX or fetch API to send requests
}
<?php
if ($_SERVER['REQUEST_METHOD'] === 'GET') {
$videoId = $_GET['videoId'];
if ($videoId) {
$videoUrl = "https://www.youtube.com/watch?v=$videoId";
// Use youtube-dl or ffmpeg to download the video
// Execute the command to download the video
// Ensure proper error handling and security measures
} else {
echo 'Invalid video ID';
}
}
?>
