Your very problem is that you are NOT encoding the URL data, so the
browser is trying to do it for you, only it can't be sure whether & is
supposed to be data or is supposed to separate your URL arguments.
http://php.net/urlencode
You may also want to just include the switch.php whenever userLangChoice
is set in the URL:
----------- langchoic.inc -------------
<?php
if (isset($_GET['userLangChoice'])){
setCookie($_GET['userLangChoice']);
}
?>
You can simply: <?php include 'langchoice.inc'?> on every page or in a
globals file you already include, and then you're not wasting a bunch of
HTTP connections bouncing around with the header or worrying about your
URL getting munged.
<?php
include 'langchoice.inc';
echo "<a href=\"$_SERVER[PHP_SELF]?userLangChoice=fr\">French</a>";
echo "<a href=\"$_SERVER[PHP_SELF]?userLangChoice=en\">English</a>";
?>
