Creating 'Previous - Next Buttons' Logic - Novice Question

Novice Question: I would like to create a set of pages that could use some kind of logic to have "previous - next buttons "so that when the button was clicked it would automatically go to the next page - or the previous page. I know very little about PHP ... however, I am hoping that there is some kind of preset " open source" php code that I might be able to use. I can envision something like this: - An 'include page' that might store an array of the list of pages such as: start array... pos1 = page1.htm pos2 = page17.htm pos3 = page5.htm etc..... stop array... - then a variable could be set for the current page such as: thispage = 2 - Place on the array equals position 2 (page17.htm) then the next button would add 1 to the current place on the array- (pos3) - and the previous button would be minus 1 place on the array - (pos1) ... that type of thing Q: Is there any "open source" code template that I can check out like this? -- Thanks - RevDave CoolCat@hosting4days.com [db-lists]
