    I have this script, however do you use $EmailRegister or $saniterad_a

@$saniterad_a=filter_var($EmailRegister, FILTER_SANITIZE_EMAIL);

if (@$UserRegister) {
if (@$PassRegister) {
if (@!filter_var($saniterad_a, FILTER_VALIDATE_EMAIL) {
die(”No email entered!);
} else {
@$UserRegister=$_POST[’UserRegister’]; # Authentication
@$PassRegister=$_POST[’PassRegister’]; # Authentication
@mail($EmailRegister

To use $EmailRegister or $saniterad_a on last variable in this script?
