Note about first argument when calling the constructor:
?C if true, instance will have initially exactly same query string as PHP received when user accessed the page
?C if false, instance will be empty.
<?php
// Imagine that user puts "test.php?name=JamesBond&age=30" into browser, then??
$query = new HttpQueryString(); // query is "name=JamesBond&age=30". (First argument is true by default.)
$query = new HttpQueryString(false); // query is empty
$query = new HttpQueryString(true, 'age=31'); // query is "name=JamesBond&age=31", name was preserved, age was updated
$query = new HttpQueryString(false, 'age=31'); // query is "age=31"
?>
Second argument can be string and associative array, same as for HttpQueryString->set() method.
