php problem with russian language

Question

i get page in utf-8 with russian language using curl. if i echo text it show good. then i use such code

$dom = new domDocument; 

        /*** load the html into the object ***/ 
        @$dom->loadHTML($html); 

        /*** discard white space ***/ 
        $dom->preserveWhiteSpace = false; 

        /*** the table by its tag name ***/ 
        $tables = $dom->getElementsByTagName('table'); 

        /*** get all rows from the table ***/ 
        $rows = $tables->item(0)->getElementsByTagName('tr'); 

        /*** loop over the table rows ***/ 
        for ($i = 0; $i <= 5; $i++)
        { 
            /*** get each column by tag name ***/ 
            $cols = $rows->item($i)->getElementsByTagName('td'); 

            echo $cols->item(2)->nodeValue; 

            echo '<hr />'; 
        } 

$html contains russian text. after it line echo $cols->item(2)->nodeValue; display error text, not russian. i try iconv but not work. any ideas?

Answer 1

I suggest use mb_convert_encoding before load UTF-8 page.

    $dom = new DomDocument();   
    $html = mb_convert_encoding($html, 'HTML-ENTITIES', "UTF-8");
    @$dom->loadHTML($html);

OR else you could try this

    $dom = new DomDocument('1.0', 'UTF-8');
    @$dom->loadHTML($html);
    $dom->preserveWhiteSpace = false;
    ..........
    echo html_entity_decode($cols->item(2)->nodeValue,ENT_QUOTES,"UTF-8");
    .......... 

Answer 2

The DOM cannot recognize the HTML's encoding. You can try something like:

$doc = new DOMDocument();
$doc->loadHTML('<?xml encoding="UTF-8">' . $html);

// taken from http://php.net/manual/en/domdocument.loadhtml.php#95251

Answer 3

mb_convert_encoding($html, 'HTML-ENTITIES', "UTF-8");

The same thing worked for PHPQuery.

P.S. I use phpQuery::newDocument($html);

instead of $dom->loadHTML($html);
