What are some potential methods for creating an online video generator using PHP?

Creating an online video generator using PHP involves dynamically generating video content based on user input or predefined templates. One method to achieve this is by using a combination of PHP for server-side processing and a video editing library or API for video manipulation. By integrating PHP with a video editing tool, you can automate the creation of personalized videos for users on the fly.

// Example code using FFmpeg for video generation
$videoFile = 'output.mp4';
$command = 'ffmpeg -i input.mp4 -vf "drawtext=text=\'Hello World\':fontfile=arial.ttf:fontsize=24:fontcolor=white:x=50:y=50" ' . $videoFile;
exec($command);

// Output the generated video file to the user
header('Content-Type: video/mp4');
header('Content-Disposition: attachment; filename="' . $videoFile . '"');
readfile($videoFile);

// Clean up the generated video file
unlink($videoFile);
