php - Send Email from Localhost XAMPP

May I know how to send an email from localhost to gmail or other email accounts? I already make research regarding this matter and tried to do it but still can not send the email. Below are my sendmail.ini and php.ini files that I edit,

sendmail.ini

smtp_server=smtp.gmail.com
smtp_port=465
smtp_ssl=ssl
error_logfile=error.log
debug_logfile=debug.log
auth_username=khairulamran.nazri@gmail.com

auth_password=[email password]
pop3_server=
pop3_username=
pop3_password=
force_sender=khairulamran.nazri@gmail.com
force_recipient=
hostname=smtp.gmail.com

php.ini - mail function

SMTP = smtp.gmail.com
smtp_port = 465
sendmail_path = "\"C:\xampp\sendmail\sendmail.exe\" -t"
mail.add_x_header=Off

contact.php - to send the email

if(isset($_POST['submitted'])){
    $name=$_POST['name'];
    $to=$_POST['email'];
    $hp=$_POST['hp'];
    $subject="Test";
    $msg="Thank you for Register. Your Name is ".$name." and Hp no. is ".$hp;
    $header="khairulamran.nazri@gmail.com";
    $success=mail($to,$subject,$msg,$header);
    if($success==true){
        echo "Email send successfully ";

    } else{
        echo "Error sending email";
    }
}
?>

If click Submit, it will not send the email that have been submitted.

Try to use mailer library. I had used and it will work perfectly.
Follow this. https://github.com/PHPMailer/PHPMailer

You would need to only enter your gmail credentials and after that it will work.
