php and js-ajax acting funny (explanation inside) - php

Question

I am having trouble with this ajax. The return is funny. The switch seems to always evaluate as though #about is true. And include the rest of the switch statement in the #page variable. For instance my PHP code prints this (as well as the #about that it is supposed to) the code at the bottom should clarify what I mean.
To recap it echoes everything past the first $page ='
on my page I see this below what it is supposed to echo
';
break;
case '#register' :
$page = 'k';
break;
case '#contact' :
$page = 'a';
break;
case '#a' :
$page = ' b';
break;
case '#b' :
$page = '<p> c</p>';
break;
default;
echo "def";
}
echo $page;
Not to mention it wont even work for #contact, or #a, #b...etc. I am not sure why. Regardless of the url passed it appears as though #about is called with what it returns (even though it returns about and more).
I would really appreciate some help! Thank you
Here is my code:
the js =]
$(document).ready(function () {
//highlight the selected link
$('a[href=' + document.location.hash + ']').addClass('selected');
//Seearch for link with REL set to ajax
$('a[rel=ajax]').click(function () {
//grab the full url
var hash = this.href;
//remove the # value
hash = hash.replace(/^.*#/, '');
//clear the selected class and add the class class to the selected link
$('a[rel=ajax]').removeClass('selected');
$(this).addClass('selected');
//hide the content
$('#content').hide();
console.log(this.href);
//run the ajax
getPage();
//cancel the anchor tag behaviour
return false;
});
});
function pageload(hash) {
//if hash value exists, run the ajax
if (hash) getPage();
console.log("k");
}
function getPage() {
//generate the parameter for the php script
var data = 'page=' + encodeURIComponent(document.location.hash);
$.ajax({
url: "loader.php",
type: "GET",
data: data,
cache: false,
success: function (html) {
//add the content retrieved from ajax and put it in the #content div
$('#content').html(html);
//display the body with fadeIn transition
$('#content').fadeIn('slow');
}
});
}
the php =]
switch($_GET['page']) {
case '#about' :
$page = ' HTML stack overflow formats it, anyways';
break;
case '#register' :
$page = 'k';
break;
case '#contact' :
$page = 'a';
break;
case '#a' :
$page = ' b';
break;
case '#b' :
$page = '<p> c</p>';
break;
default;
echo "def";
}
echo $page;
thank you again!

Also in the php file, try putting this on top of the script:
header("Content-Type: text/html");
