PHP change DOM useragent

I have this simple code to get the title of any page

<?php
    $doc = new DOMDocument();
    @$doc->loadHTMLFile('http://www.facebook.com');
    $xpath = new DOMXPath($doc);
    echo $xpath->query('//title')->item(0)->nodeValue."\n";
?>

It is working fine on all pages that I have tried but not in Facebook.

When I try in Facebook it is not showing Welcome to Facebook - Log In, Sign Up or Learn More, but it is showing Update Your Browser | Facebook.

I think there is a problem with useragent. So is there a way to change the useragent or is there any other solution for this?

Solution

  • You can set the user agent in php.ini, without the need for curl. Just use the below lines before you load the DOMDocument

    $agent = "Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)";
ini_set('user_agent', $agent);

    And then your code:

    $doc = new DOMDocument();
@$doc->loadHTMLFile('http://www.facebook.com');
$xpath = new DOMXPath($doc);
echo $xpath->query('//title')->item(0)->nodeValue."\n";
