Filter function issue

[vaidyamanishjoshi]

Filter function is adding single quotes and then creating issue..

e.g. if we filter email input value and then tried php validation for email, it shows invalid email.

$email = $database->filter($_POST['email']);
if(!empty($email){
if(filter_var($email,FILTER_VALIDATE_EMAIL) === false){
$msg[] = "Invalid Email Id !";
$error = true;
}
}

It always return Invalid Email error. While in Mysqli Class by you, it is working ok...
