What are some best practices for handling email delivery errors and notifications in PHP scripts?

When sending emails from PHP scripts, it is important to handle delivery errors and notifications properly to ensure the reliability of your email system. One common practice is to use PHP's built-in error handling functions to capture any errors that occur during the email sending process and log them for later review. Additionally, you can set up email notifications to alert you when an email delivery fails, allowing you to take immediate action to resolve the issue. 

// Example code to handle email delivery errors and notifications in PHP

// Set up error handling for email sending
set_error_handler(function($errno, $errstr, $errfile, $errline) {
    // Log the error details to a file or database
    $errorLog = "Error: $errstr in $errfile on line $errline";
    error_log($errorLog, 3, "error.log");
});

// Send email
$to = "recipient@example.com";
$subject = "Test Email";
$message = "This is a test email.";
$headers = "From: sender@example.com";

if (!mail($to, $subject, $message, $headers)) {
    // If email delivery fails, send a notification
    $errorNotification = "Email delivery failed for $to: $subject";
    mail("admin@example.com", "Email Delivery Error", $errorNotification);
}
