How does the use of HTTPS affect the ability to send emails using PHP's mail() function?

When using HTTPS, the mail() function in PHP may not work properly due to security restrictions. To solve this issue, you can configure your SMTP settings in the php.ini file to use a secure email server for sending emails. This ensures that emails are sent securely over HTTPS. 

// Set the SMTP settings in php.ini file
ini_set("SMTP","smtp.yourmailserver.com");
ini_set("smtp_port","25");
ini_set("sendmail_from","your_email@yourdomain.com");

// Send email using mail() function
$to = "recipient@example.com";
$subject = "Test Email";
$message = "This is a test email.";
$headers = "From: your_email@yourdomain.com";

mail($to, $subject, $message, $headers);
