If you are avoiding JavaScript, you will need to save the values in @array1 as a HIDDEN field on the form.

That way, when the SUBMIT is clicked, @array1 is returned via the param name of the hidden field.
You can use that to compare with what you receive with the form fields.

This method does have a potential security issue if the user tampers with the hidden fields.
To avoid that, you may add an additional hidden "checksum" type field, or, preferably, persist the checksum somewhere in the database, or local temp file, or even a session variable.

        Software efficiency halves every 18 months, thus compensating for Moore's Law.
