    Probably because you are using DOMDocument() wrong. Do the following:

    
<?php

$html = <<<EOF
<head>
<meta name="Description" content=""/>
<meta name="Keywords" content=""/>

<title>abc what I wish to display</title>
</head>
EOF;

$dom = new DOMDocument();
$dom->loadHTML($html);
$nodes = $dom->getElementsByTagName('title');
$title = $nodes->item(0)->nodeValue;

print $title;

?>
    PHP:

    What you can do is create a 'global.php' file and put your title in there for example.

    1. global.php
    
<?php
$sitetitle = "Your title here";
?>
    HTML:
    Then you can display it globally on as many pages as you want by doing this below.

    2. Index.php
    
<?php
require('global.php');
?>
<html>
<head>
<title><?php echo $sitetitle; ?></title>
</head>
<body></body>
</html>
    HTML:
