ok, this is may problem:
suppose I reach page ‘B’ clicking a button in page ‘A’, then reach page ‘C’ starting from page ‘B’ etc..
because I know path, in page B I can put <a href="/pathBackToPageA">Go Back </a> to go back form B to A and so on and after I could return page A going back from C to B and the to A.
Suppose now you want reach page B starting from page D obviously you would return to D going back form C to B and from B to D, but in page B the ‘Go Back’ button is pointing A . So wich is the way, if you want have only a button to go back the right page ?

I have a pagination that is quite old, I have been succesful in getting it to work with php8.1 but I have one error I can not fix, and would like some help if possible please.
