Php code

function file_get_contents_curl($url){
            $ch = curl_init();
            curl_setopt($ch, CURLOPT_HEADER, 0);
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
            curl_setopt($ch, CURLOPT_URL, $url);
            curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
            $data = curl_exec($ch);
            curl_close($ch);
            return $data;
        }

        $html = file_get_contents_curl($pageurl);

        $doc = new DOMDocument();
        @$doc->loadHTML($html);
        $nodes = $doc->getElementsByTagName('title');

        $titleBackUp = $nodes->item(0)->nodeValue;

        $metas = $doc->getElementsByTagName('meta');

        for ($i = 0; $i < $metas->length; $i++){
            $meta = $metas->item($i);
            if($meta->getAttribute('name') == 'title')
                $title = $meta->getAttribute('content');
        }

The title is Мастило – В ръцете ти е най-добре [HQ] and i’m getting

ÐаÑÑило – Ð ÑÑÑеÑе Ñи е най-добÑе [HQ]

I try also with

 curl_setopt( $ch, CURLOPT_ENCODING, "UTF-8" );

but it dosent work.

I try with html_entity_decode but is not working

Answer 1

This can happen if the document itself doesn’t contain a <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> tag.

You can try either of the following:

1. Let DomDocument load the HTML directly from the server (i.e. use ->loadHTMLFile())

2. Prefix the document with aforementioned meta tag before running it through ->loadHTML().

For example, you could do this:

libxml_use_internal_errors(true);
$doc->loadHTML('<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />' . $html);
libxml_clear_errors();

It’s a hack to let libxml know it’s supposed to read utf-8 data … it’s not possible to pass that encoding via ->loadHTML().
