How do I test the PHP mail() function for sending emails?

To use the PHP mail() function, ensure either the "To" or "From" email address is an active email account created in your hosting account. Below is a sample script to test the function:

";
$to = "info@clientdomain.com";
$subject = "Test Email";
$body = "This is a test message.";

if (mail($to, $subject, $body, $from)) {
 echo "Email sent successfully to: $to";
} else {
 echo "Email sending failed.";
}
?>

Replace test@example.com and info@clientdomain.com with your actual email addresses. Ensure your script is correctly configured to avoid delivery issues.
