Answer 1

Use strip_tags().

Answer 2

You can parse the HTML using DOMDocument::loadHTMLFile and extract what you need.

$doc = new DOMDocument();
$doc->loadHTMLFile("data.html");
$metaTags = $doc->getElementsByTagName('meta');
// Process $metaTags

Answer 3

surely it can be done :

just look at this function and use it as u like :

function html2txt ( $document )
{
        $search = array ("'<script[^>]*?>.*?</script>'si",  // strip out javascript
                "'<[\/\!]*?[^<>]*?>'si",        // strip out html tags
                "'([\r\n])[\s]+'",          // strip out white space
                "'@<![\s\S]*?�[ \t\n\r]*>@'",
                "'&(quot|#34|#034|#x22);'i",        // replace html entities
                "'&(amp|#38|#038|#x26);'i",     // added hexadecimal values
                "'&(lt|#60|#060|#x3c);'i",
                "'&(gt|#62|#062|#x3e);'i",
                "'&(nbsp|#160|#xa0);'i",
                "'&(iexcl|#161);'i",
                "'&(cent|#162);'i",
                "'&(pound|#163);'i",
                "'&(copy|#169);'i",
                "'&(reg|#174);'i",
                "'&(deg|#176);'i",
                "'&(#39|#039|#x27);'",
                "'&(euro|#8364);'i",            // europe
                "'&a(uml|UML);'",           // german
                "'&o(uml|UML);'",
                "'&u(uml|UML);'",
                "'&A(uml|UML);'",
                "'&O(uml|UML);'",
                "'&U(uml|UML);'",
                "'&szlig;'i",
                );
        $replace = array (  "",
                    "",
                    " ",
                    "\"",
                    "&",
                    "<",
                    ">",
                    " ",
                    chr(161),
                    chr(162),
                    chr(163),
                    chr(169),
                    chr(174),
                    chr(176),
                    chr(39),
                    chr(128),
                    "ä",
                    "ö",
                    "ü",
                    "�",
                    "�",
                    "�",
                    "�",
                );

        $text = preg_replace($search,$replace,$document);

        return trim ( $text );
}
