adding get variables to url?

hi, i have a question, that i didnt manage to figure out myself.
you know when you have a search engine, and you want to apply filters, and sort stuff by given parameter?
if you simply make this:
it wont keep both filters, if you click the first one, and then click the second one, it will replace the first clicked.
my workaround for this so far:
but thats not good when you have like 10 filters (wich is my case) you'll have an extense code for each anchor href...
so i was trying to figure out a way to simply add variables to a $url variable, like if $_GET[variable] is set, $url.="add variable", and if that variable is already set, replace if its different, or keep if its equal, but i dont know if thats possible cuz i didnt manage to make it.
is it doable?
thanks in advance!

<a href="?filter1=low">low prices</a>
<a href="?filter2=best">best rated</a>

Code: Select all
<a href="?filter1=low&filter2=<?php echo $_GET['filter2']; ?>">low prices</a>
<a href="?filter2=best&filter1=<?php echo $_GET['filter1']; ?>">best rated</a>
