How can the issue of duplicate IDs be prevented when multiple articles are submitted simultaneously in PHP?

Issue: The issue of duplicate IDs can be prevented by generating unique IDs for each article before inserting them into the database. One way to achieve this is by using UUIDs (Universally Unique Identifiers) instead of relying on auto-incremented IDs. 

// Generate a UUID for each article before inserting into the database
$uuid = uniqid();
// Insert article into the database with the generated UUID
$query = "INSERT INTO articles (id, title, content) VALUES ('$uuid', '$title', '$content')";
// Execute the query
$result = mysqli_query($conn, $query);
