Add variables to $_GET for url link

When working with links containing forms on the same page, you sometimes don’t want to lose the data. Especially if you switch languages after a search. You can easily build a query with old and new variables. //php $variables = array_merge($_GET, array(“a” => “value1”, “b” => “value2”)); $queryString = http_build_query($variables); //Result: ?old1=that&old2=this&a=value1&b=value2
