pass parameters to pagination url

Question

I am thing of a way to pass about 15 parameters to a url pagination:

for example I have:

$input = $_GET['input'];
$categories = $_GET['category'];
$state = $_GET['state'];
$zipcode = $_GET['zipcode'];

I could do it this way and works fine:

 $paginate.= "<a href='$targetpage?page=$prev&input=".$_GET['input']."& 
 category=".$_GET['category']."&state=".$_GET['state']."& 
 zipcode=".$GET['zipcode']."'>Previous</a>";

But I have a lot more Parameters to pass. Could someone show me how it's done using an array or anything better?

Thank you

Yo can use this function:
http_build_query

php.net example:

<?php
$data = array('foo'=>'bar',
              'baz'=>'boom',
              'cow'=>'milk',
              'php'=>'hypertext processor');

echo http_build_query($data) . "\n";
echo http_build_query($data, '', '&amp;');

?>

Output:

foo=bar&baz=boom&cow=milk&php=hypertext+processor
foo=bar&baz=boom&cow=milk&php=hypertext+processor
