HTML

<input type="text" name="links" id="links">
<div id="result" ></div>

<script type="text/javascript" src="jquery.js"></script>
 <script>
 $(document).ready(function(){
  $("#links").keyup(function(){
fetch();
 });
 });
 function fetch()
 {
  var linkdata= document.getElementById('links').value;

  if(linkdata.length>0)

  $("#result").html('<img src="ajax-loader.gif"/>');
  
 $.ajax({
 type:'POST',
 url:'result.php',
 cache:false,
 data:{link:linkdata},
 success:function(response){
$('#result').slideDown(); 
document.getElementById('result').innerHTML= response;

 </script>

CSS

img
{
width:auto;
height:auto;
}
#result
{
width:450px;
height:auto;
margin-top:5px;
}

result.php
This webpage contains a file_get_contents() function of PHP to get remote content which loads URL data. After getting data we are splitting it separately using preg_match() function to get title, meta description and image.

<?php
$linkss=$_POST['link'];
if($linkss){
function get_content($url){

$vikash = @file_get_contents($url);
$res = preg_match("/<title>(.*)<\/title>/", $vikash, $title_matches);

$title = preg_replace('/\s+/', ' ', $title_matches[1]);

$title = trim($title);

preg_match('/<img[^>]+>/',$vikash, $result); //store image in $result

$image=$result[0];

$tags = get_meta_tags($url);
 
echo $image;
echo '<a href="'.$url.'">'.'<h1>'.$title.'</h1>'.'</a>';
echo $tags['description'];  // a php manual
}
get_content($linkss);
}
?>
