How can PHP be used to automatically encrypt and delete uploaded links after a specified time period?

To automatically encrypt and delete uploaded links after a specified time period in PHP, you can generate a unique encrypted link for each upload, store the link and expiration time in a database, and set up a cron job to periodically check for expired links and delete them. 

// Generate a unique encrypted link for the uploaded file
$uploadLink = md5(uniqid(rand(), true));

// Store the link and expiration time in a database
$expirationTime = time() + (24 * 60 * 60); // 24 hours expiration time
$query = "INSERT INTO uploaded_links (link, expiration_time) VALUES ('$uploadLink', '$expirationTime')";
// Execute the query to store the link in the database

// Set up a cron job to periodically check for expired links and delete them
// You can create a separate PHP script to do this and schedule it to run at regular intervals using a cron job
// The script should query the database for expired links and delete them
