Are there any specific PHP functions or libraries that can help with handling video files on a server?

Handling video files on a server typically involves tasks such as uploading, storing, retrieving, and possibly processing the video files. PHP provides several functions and libraries that can help with these tasks, such as the `move_uploaded_file()` function for uploading files, the `file_get_contents()` function for reading file contents, and libraries like FFmpeg for video processing.

// Example code for uploading a video file
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["video"]["name"]);

if (move_uploaded_file($_FILES["video"]["tmp_name"], $target_file)) {
    echo "The file ". basename( $_FILES["video"]["name"]). " has been uploaded.";
} else {
    echo "Sorry, there was an error uploading your file.";
}
