Auto mail notification after expire date from database in php

To send an auto mail notification after a record expires from a database in PHP, you can use the following steps:

Step 1: Set up your database and table

Create a table in your database to store the records with an expiration date. For example:

CREATE TABLE records (
  id INT PRIMARY KEY,
  name VARCHAR(255),
  email VARCHAR(255),
  expiration_date DATE
);

Step 2: Write a PHP script to check for expired records

Create a PHP script that connects to your database and checks for records that have expired. You can use a cron job to run this script periodically (e.g., every hour, daily, etc.).

<?php
// Connect to the database
$conn = mysqli_connect("localhost", "username", "password", "database_name");

// Check connection
if (!$conn) {
    die("Connection failed: ". mysqli_connect_error());
}

// Query to get expired records
$query = "SELECT * FROM records WHERE expiration_date <= CURDATE()";
$result = mysqli_query($conn, $query);

// Loop through the results and send notifications
while ($row = mysqli_fetch_assoc($result)) {
    // Get the record ID, name, and email
    $id = $row['id'];
    $name = $row['name'];
    $email = $row['email'];

    // Send a notification email
    $subject = "Record Expired: $name";
    $message = "Dear $name, your record has expired. Please contact us to renew.";
    $headers = "From: [email protected]";
    mail($email, $subject, $message, $headers);

    // Update the record status to "expired"
    $update_query = "UPDATE records SET status = 'expired' WHERE id = $id";
    mysqli_query($conn, $update_query);
}

// Close the database connection
mysqli_close($conn);
?>

Step 3: Schedule the PHP script to run periodically

Use a cron job to schedule the PHP script to run periodically. For example, you can run the script every hour using the following command:

crontab -e

Add the following line to the cron table:

0 * * * * /usr/bin/php /path/to/your/script.php

This will run the script every hour at the top of the hour.
