Use prepared statements to securely save the file path from a $_POST form.
Retrieve the path using fetch() and echo it into the src attribute of an HTML tag. 2. Common Challenges
Use a VARCHAR or TEXT column to store the filename or path.
Most developers store the (e.g., /uploads/video.mp4 ) in a database rather than the video file itself to maintain performance.
PHP has default limits (e.g., upload_max_filesize ) that often block larger .mp4 uploads before they even reach your PDO script.
