Htaccess PHP ignore all gets except of first

Question

My $GET parameter could be url with another paramenters (mysite.co/index.php?q=anothersite.co?id=2) and i need to ignore them.

But im getting lost them (mysite.co/index.php?q=anothersite.co) after going to the url.

How i can fix it? Without decoding url.

Answer 1

you have to use & instead of another ?

this should work

mysite.co/index.php?q=anothersite.co&id=2

EDIT:

$encoded = encode("http://anothersite.co?id=2");

and then

mysite.co/index.php?q=$encode
