What is the purpose of using ffmpeg in PHP for generating thumbnails from videos?

When working with videos in PHP, one common task is to generate thumbnails from the videos. This can be achieved by using ffmpeg, a powerful multimedia framework that can manipulate videos. By utilizing ffmpeg in PHP, we can extract frames from the video at specified time intervals to create thumbnails. 

// Path to the video file
$videoPath = 'path/to/video.mp4';

// Path to save the thumbnail image
$thumbnailPath = 'path/to/thumbnail.jpg';

// Execute ffmpeg command to generate thumbnail
exec("ffmpeg -i $videoPath -ss 00:00:05 -vframes 1 $thumbnailPath");

// Check if thumbnail image was successfully generated
if(file_exists($thumbnailPath)) {
    echo 'Thumbnail generated successfully!';
} else {
    echo 'Failed to generate thumbnail.';
}
