    <?php


     $content=file_get_contents('example.com');

   // it would return html <head>..... 
  <title>Example.com</title>

I want to extract example.com from title

  $title=pick('<title>','</title>',$content);

   Echo $title;

And it would show Example.com

You can use substr to substring the HTML content and stripos to find the title tags.
I add 7 to the position to remove the tag.

$html = file_get_contents('example.com');
$pos = stripos($html, "<title>")+7;
echo substr($html, $pos, stripos($html, "</title>")-$pos);

Example:

This assumes there is only one title tag on the page, if there is more then it will get the first title tag.

You can use file_get_content() instead of $string. 

    $string = "<title>MY TITLE</title>";

    $pattern = "/<title>(.*?)<\/title>/";

    preg_match($pattern, $string, $matches);

    echo "RESULT : ".$matches[1];

Try using PHP's simple xml parser to read the title node.

$xml = simplexml_load_string(file_get_contents('example.com'));
echo $xml->head->title;
