Added $opts for setting a custom from name and email adress

function email($to,$subject,$body,$opts=[],$attachment=false){
	$db = DB::getInstance();
	$query = $db->query("SELECT * FROM email");
	$results = $query->first();

	$mail = new PHPMailer;

	$mail->SMTPDebug = $results->debug_level;               // Enable verbose debug output
  if($results->isSMTP == 1){$mail->isSMTP();}             // Set mailer to use SMTP
	$mail->Host = $results->smtp_server;  									// Specify SMTP server
	$mail->SMTPAuth = $results->useSMTPauth;                // Enable SMTP authentication
	$mail->Username = $results->email_login;                 // SMTP username
	$mail->Password = htmlspecialchars_decode($results->email_pass);    // SMTP password
	$mail->SMTPSecure = $results->transport;                            // Enable TLS encryption, `ssl` also accepted
	$mail->Port = $results->smtp_port;                                  // TCP port to connect to

	if(isset($opts['email']) && isset($opts['name'])){
  $mail->setFrom($opts['email'], $opts['name']);
}else{
  $mail->setFrom($results->from_email, $results->from_name);
}

	$mail->addAddress(rawurldecode($to));                   // Add a recipient, name is optional
  if($results->isHTML == 'true'){$mail->isHTML(true); }                  // Set email format to HTML

	$mail->Subject = $subject;
	$mail->Body    = $body;

	$result = $mail->send();

	return $result;
