file_get_html() not working?

Question

I am trying to get the title and meta description data of page by providing it url of target page but file_get_html() always return FALSE value. Any suggestions? by the way I have enabled the php extension php_openssl.

<?php
    include("inc/simple_html_dom.inc.php");
    $contents = file_get_html("https://www.facebook.com"); 
    if($contents !=FALSE) //always skips if condition
    {
        foreach($contents->find('title') as $element) 
        {
            $title = $element->plaintext;
        }

        foreach($contents->find('meta[description]') as $element) 
        {
            $meta_description = $element->plaintext;
        }
        $output = array('title'=>$title, 'meta'=> $meta_description);
        echo json_encode($output);
    }
    else
    {
        echo"Couldn't load contents";
    }
?>

UPDATE:

So file_get_html() works fine now but any idea about dealing with facebook update browser message?

Answer 1

<?php
    $ch = curl_init('https://www.facebook.com/');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    /* 
     * XXX: This is not a "fix" for your problem, this is a work-around.  You 
     * should fix your local CAs 
     */
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

    /* Set a browser UA so that we aren't told to update */
    curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/34.0.1847.116 Safari/537.36');

    $res = curl_exec($ch);

    if ($res === false) {
        die('error: ' . curl_error($ch));
    }

    curl_close($ch);

    $d = new DOMDocument();
    @$d->loadHTML($res);

    $output = array(
        'title' => '',
        'meta'  => ''
    );

    $x = new DOMXPath($d);

    $title = $x->query("//title");
    if ($title->length > 0) {
        $output['title'] = $title->item(0)->textContent;
    }

    $meta = $x->query("//meta[@name = 'description']");
    if ($meta->length > 0) {
        $output['meta'] = $meta->item(0)->getAttribute('content');
    }

    print_r($output);
?>

This displays:

Array
