URIs as variables

Newbie question here. I am trying to pass a varaible containing a URI across a few scripts. Basically, the first script get's a query string including the URI (eg http://foo.bar/script1.php?url=script2.php?var1=a&var2=b). Now, script1 contains a form pointing to script3 so basically, I have the user form and then: <? echo "<INPUT TYPE=\"HIDDEN\" NAME=\"url\" VALUE=\"$url\">"; ?> (I have register-gloabls enabled and am not sure whether the call to script1 will be POST or GET) This creates a slight problem, as, using the above example once again, PHP will send the browser the line: <INPUT TYPE="HIDDEN" NAME="url" VALUE="script2.php?var1=a"> But it totally chops off everything from the "&" and onwards. How can I fix it to get the entire URI?
