A page index.php receives 4 different GET parameters id, k, page, cid, cid2
id: page id
k: search keyword
page: page number
cid: Category 1
cid2: Category 2
index.php?id=1
index.php?k=P中文&page=1
index.php?cid=1&cid2=1
Put them all in one index.php to handle GET requests. How to do it? I can do one GET, but I can’t do so many.
