Find out if a domain name exists

You can user CURL to request a page and evaluate the response to determine if the page exists.

function verify_domain($domain='') {
	$url = "http://" . $domain;
	$ch = curl_init($url);
	curl_setopt($ch, CURLOPT_NOBODY, true);
	$code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
	if($code &gt;= 400) {
		return false;
	return true;

Render jQuery Mobile on Desktop Computers

If you designed a jQuery Mobile site that it is intended for small size screens, that does not mean that someone will never open your app from a desktop computer. Obviously, an app that was design for an actual screen size of 320 px will not look right if it is opened on a desktop computer.

To prevent the app from looking awful, we can apply CSS to restrict the jQuery Mobile pages from rendering at a width higher that, let’s say, 480 px.

@media only screen and (min-width : 480px) {
	div[data-role="page"] > *[data-role="header"],
	div[data-role="page"] > *[data-role="footer"] {
	    width: 480px !important;
        left: 50%;
        margin-left: -240px;
	div[data-role="page"] {
	    width: 480px !important;
        left: -240px !important;
        margin-left: 50%;
	/* add your favorite image to the background */
	body {
		background-image: url('my-favorite-background.jpg');
		background-attachment: fixed;

Setting Up The Default Values Of The jQueryMobile Preloader

Here is a quick example that shows how to setup the default values of the jQueryMobile preloader:

$(document).on("mobileinit", function () {
    $.mobile.loader.prototype.options.text = "loading";
    $.mobile.loader.prototype.options.textVisible = false;
    $.mobile.loader.prototype.options.theme = "a";
    $.mobile.loader.prototype.options.html = "";
