In this style sheet only thing need to observe is #databox. It is display:none It will make it shown in jquery code when ajax is success.


$str = file_get_contents($url);
//to get the title
function getTitle($str){
return $title[1];
//to get meta description
function getMetaDesc($url) {
$metas = get_meta_tags($url);
return $metas["description"];
//to get the img.
function getImg($str){
return $img[1];
//json formation
echo '{"title":"'.getTitle($str).'","meta":"'.getMetaDesc($url).'","img":"'.getImg($str).'"}';

This code we use to get the info Page Title, Meta Description, Image. We will sent them back in JSON format. That’s it! hope you like it. Please share it with your friends.
