html - Passing data from page to page in PHP -

well, have new project, , i've not done before, far good. in need of having pass data 1 page another, , there no limit amount of data gets passed.

at first, thinking of post-ing it, , when each page loads, grab post data, , store in array, me sounds bit on complicated or want do.

then thought html5 , localstorage, since there limit on localstorage, , fact majority of users browsers still don't support yet (that is, majority of clients customers browsers), that's big no no, @ point.

so, i'm out of ideas.

here's i'm trying do, sounds pretty simple me, yet can't figure out how go it:

on given page, there on hundred links, each link represents either name of product or information product, if click on of these links, , move off page, information product name clicked on follow them new page, , same thing happens on new page, if click on 1 of links again, new info added existing information, , passed on whatever new page visit.

i guess works shopping cart, whereby if user adds cart, cart, , data inside follows them right checkout.

i'd appreciate @ all?

i think want use database purpose. each page pulls data out of database user clicks through. guarantee hundred or objects database, time access database each new page order of magnitude smaller round trip http time user's browser.
