In what ways can PHP developers optimize email sending functionality to avoid encoding issues in the future?

To optimize email sending functionality and avoid encoding issues in the future, PHP developers can use the mb_send_mail() function instead of the traditional mail() function. This function allows developers to specify the character encoding for the email content, ensuring that special characters are properly handled. 

// Set the email content type and character encoding
$subject = "Subject of the email";
$message = "Message content with special characters like é, ü, etc.";
$to = "recipient@example.com";
$from = "sender@example.com";
$headers = "From: $from\r\n";
$headers .= "Content-Type: text/plain; charset=UTF-8\r\n";

// Send the email using mb_send_mail() function
mb_send_mail($to, $subject, $message, $headers);
