Certainly! Here's an expanded code in PHP using PHPMailer to send notification emails to invited persons for an event or birthday party. The code also includes a message about the validity of the invitation and reply options.
Make sure you have the PHPMailer library installed and properly configured. You can download it from

PHP:
<?php
require 'path/to/PHPMailer/src/PHPMailer.php';
require 'path/to/PHPMailer/src/SMTP.php';
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\SMTP;
function calculateDates($startDate, $endDate) {
// Calculate birth age
$birthAge = time() - strtotime($startDate);
$years = floor($birthAge / (365 * 24 * 60 * 60));
// Calculate expiration age
$expirationAge = time() - strtotime($endDate);
$expirationYears = floor($expirationAge / (365 * 24 * 60 * 60));
// Calculate expiration date
$expirationDate = date("Y-m-d", strtotime($endDate));
// Calculate notification date before expiration date
$notificationDate = date("Y-m-d", strtotime($endDate . "-7 days")); // 7 days before expiration
// Calculate birth date
$birthDate = date("Y-m-d", strtotime($startDate));
return [
"birthAge" => $years,
"expirationAge" => $expirationYears,
"expirationDate" => $expirationDate,
"notificationDate" => $notificationDate,
"birthDate" => $birthDate,
];
}
// Example usage
$result = calculateDates('1990-01-01', '2050-12-31');
// Send notification email
$smtpHost = 'your_smtp_host'; // Update with your SMTP host
$smtpUsername = 'your_smtp_username'; // Update with your SMTP username
$smtpPassword = 'your_smtp_password'; // Update with your SMTP password
$smtpPort = 587; // Update with your SMTP port
$mail = new PHPMailer(true);
try {
// SMTP configuration
$mail->isSMTP();
$mail->Host = $smtpHost;
$mail->SMTPAuth = true;
$mail->Username = $smtpUsername;
$mail->Password = $smtpPassword;
$mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;
$mail->Port = $smtpPort;
// Email content
$mail->setFrom('sender@example.com', 'Sender Name');
$mail->addAddress('invited@example.com', 'Invited Person');
$mail->isHTML(true);
$mail->Subject = 'Birthday Event Notification';
$mail->Body = 'Dear invited person,<br><br>You are invited to a birthday event!<br><br>Here are some details:<br>'
. 'Birth Age: ' . $result['birthAge'] . ' years<br>'
. 'Expiration Age: ' . $result['expirationAge'] . ' years<br>'
. 'Expiration Date: ' . $result['expirationDate'] . '<br>'
. 'Notification Date: ' . $result['notificationDate'] . '<br>'
. 'Birth Date: ' . $result['birthDate'] . '<br><br>'
. 'Please note that the validity of this invitation will expire 10 days upon receiving this email. '
. 'Kindly reply to this email with your response:<br>'
. '1. Accept<br>'
. '2. Decline';
$mail->send();
echo 'Notification email sent successfully.';
} catch (Exception $e) {
echo 'Notification email could not be sent. Error: ', $mail->ErrorInfo;
}
?>
In this code, the
calculateDates function calculates the birth age, expiration age, expiration date, notification date before expiration date, and birth date, just like in the previous code.
The PHPMailer library is used to send the notification emails. Make sure to update the
$smtpHost,
$smtpUsername,
$smtpPassword, and
$smtpPort with your own SMTP server details.
The code sets up the SMTP configuration and creates a new PHPMailer instance. It then sets the sender, recipient, subject, and body of the email. The body of the email includes the invitation details and the reply options (Accept or Decline).
The email is sent using the
$mail->send() method, and any errors are caught and displayed if the email fails to send.
Please make sure to adapt the code to match your specific setup, including updating the paths to the PHPMailer library and providing the correct SMTP details.
