I've spend a full day on it. Searched on the net. Saw some similar questions on satckoverflow also. but all I got disappointment.

I want to get some php code by which I can output the title and some 4-5 lines for the description of any website using php.

<?php

  $url = "http://www.drquincy.com/";

  $fp = fopen($url, 'r');
  $content = "";
  while(!feof($fp)) {
        $buffer = trim(fgets($fp, 4096));
        $content .= $buffer;
  }


  $start = '<title>';
  $end = '</title>';
  preg_match(" / $start( . * )$end / s", $content, $match);
  $title = $match[1];
  $metatagarray = get_meta_tags($url);
  $keywords = $metatagarray["keywords"];
  $description = $metatagarray["description"];
  echo " <div><strong>URL: </strong >$url</div> \n";
  echo " <div><strong>Title: </strong >$title</div> \n";
  echo " <div><strong>Description: </strong >$description</div>\n";
  echo " <div><strong>Keywords: </strong >$keywords</div>\n";

Just change the url:)

There are many ways to parse a HTML. First, you want the content itself:

$res = file_get_contents("http://www.google.com");

That assumes file_get_contents allowed to access uri. For example, you might utilize a regex:

preg_match("~<title>(.*?)</title>~", $res, $match);
$title = $match[1];

But it would be better to use a DOM parser. http://php.net/manual/en/book.xml.php, though that may be problem if the target content is not valid xml.
