What are the advantages of automatically deleting old database entries on each page load instead of using a scheduled job in PHP registration form verification processes?

When dealing with a PHP registration form verification process, automatically deleting old database entries on each page load can help improve performance and reduce the risk of data clutter. This approach ensures that only relevant data is stored in the database, leading to faster query execution times and a more efficient overall system. By deleting old entries dynamically, the database remains streamlined and optimized without the need for a separate scheduled job to clean up old data. 

// Automatically delete old database entries on each page load
$expiry_date = strtotime('-1 day'); // Define expiry date (e.g. 1 day ago)

// Connect to database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Delete old entries
$sql = "DELETE FROM registration_table WHERE registration_date < $expiry_date";
$conn->query($sql);

// Close connection
$conn->close();
