IMHO, having multiple methods independently responsible for creating a
complex URL like that, and then having a regular expression to
subsequently "alter" it is likely to be error-prone and a maintenance
nightmare.
I don't know what your exact scenario is, but if I were doing it, I
might maintain an associative array of the GET variables and values e.g.
something like:
class Foo
{
private $variables;
function bar()
{
$variables["section"] = "image";
$variables["refAction"] = "edit";
...
$variables["action"] = "move_image";
}
function fuzz()
{
$variables["section"] = "home";
$variables["refAction"] = "delete";
...
$variables["action"] = "kill_image";
}
function alter_action()
{
$variables["action"] = "edit";
}
function getQueryString()
{
// convert array contents to a query string
}
}
