Simplest way to parse a title from an HTML file using PHP functions only, no extra classes

So far I've been trying to get a simple way to stract a title from an HTML page.

This simple:

$url = "http://localhost";

Use any function to extract the title tag using only PHP functions or regular expressions, I do not want to use any external classes such as simple_html_dom or Zend_Dom... I want to do it the simple way with PHP only... can anyone post a sample code to simply extract the title tag from localhost?

I've tried using DOMdocument() class, simple_xml_parse(), and none of them with success

I tried like this: 

<?php $dom = new DOMdocument(); 
$dom->loadhtml('pag.html'); 
$items = $dom->getElementsByTagName('title');
foreach ($items as $title) { echo "title"; }

With DOM:

<?php 
$doc = new DOMDocument();
$doc->loadHTML(file_get_contents("1.html"));
$items = $doc->getElementsByTagName("title");
if($items->length > 0){
  echo $items->item(0)->nodeValue;
 }
?>

With Regular Expressions:

<?php

$html = file_get_contents('1.html');
preg_match("/<title>([^<]*)<\/title>/im", $html, $matches);
echo $matches[1];

?>

1.html

<html>
<head>
    <title>This is the title</title>
</head>
<body>
<h1>Hello</h1>
</body>
</html>

Output:

This is the title
