PHP - Setting Samesite In Php7.1.x

I have an interface with method: public function foo(string $arg1, string $arg2);

With PHP7.4, I can have a class relax the type without errors such as Dog::foo(string $arg1, $arg2) ($arg2 is not required to be a string)

I incorrectly thought I could even relax the constraint more such as Dog::foo(string $arg1){} and not even pass $arg2 because extra arguments which exceed a method's placeholders are ignored without error but I received error:  Declaration of Dog::foo(string $arg1) must be compatible with AnimalInterface::foo(string $arg1, string $arg2).

Are my only options to include $arg2=null in the relaxed methods and label the methods something $dummy1, $dummy2..., or pass them in an array (which I don't wish to do)?

Is passing extra parameters to the same method as I am doing considered bad practice, and if so what is considered the correct way?

Thanks

please help me

I have used this program for many years without problems.
My ISP urged me to upgrade PHP to 7.2 and it was working OK.
Just went to use it and I get an error when parsing my FPDF file.
Here is the error:
Connected (added this to check if connected)
Fatal error: Uncaught Error: Call to undefined method PDF::FPDF() in /homepages/30/d593365489/htdocs/Prnpdf.php:78 Stack trace: #0 /homepages/30/d593365489/htdocs/Prnpdf.php(108): PDF->PDF('L', 'mm', 'A4') #1 {main} thrown in /homepages/30/d593365489/htdocs/Prnpdf.php on line 78

I have not altered the file in any way, so why is this happening?

Is it to do with PHP upgrade?😖

Here is the file:

Please can some one help me. We have upgraded php and not i cant get the php page to correctly redirect the user to the login page if the user has not logged in and the get it to redirect to the index page. So the form sequence is as follows. User connects to index page, user clicks on link to add or delete data in mysql database, page must redirect to login page if user has not logged in, once logged in login page must redirect to add or delete page depending on the link clicked on. Addins and deleting data to the mysql database table works fine.

Below is the add,php page.
