YO!

jetzt geht’s ;-)

dazu kam noch ein kleiner Fehler bei mir ... für die es interessiert
hier der Gesamte Codeschnipsel um aus einem "formatierten"
HTML-Quellcode eine brauchbare Text-Ansicht zu bekommen:

function un_htmlentities ($string)
{
	global $trans_tbl;
	$r = strtr($string,array('„' => '"',
	                         '“' => '"',
	                         chr(132) => '"',
	                         chr(147) => '"',
		                     "„"=> '"',
			                 "“"=> '"'
	                         ));
	$r = strtr($r, $trans_tbl);
	return $r;
}

[...]
$replacer  = array("\r" => "",
                   "\n" => " ",
                   "<p>" => "\n\n",
                   "<P>" => "\n\n",
                   "<br>" => "\n",
                   "<BR>" => "\n",
                   "<br />" => "\n",
                   "<h1>" => "\n\n",
                   "<H1>" => "\n\n",
                   "<h2>" => "\n\n",
                   "<H2>" => "\n\n",
                   "<h3>" => "\n\n",
                   "<H3>" => "\n\n",
                   "&nbsp;" => " "
                   );
$content = trim(strip_tags(un_htmlentities(strtr($content,$replacer))));
$lines = explode("\n",$content);
$content = '';
foreach($lines as $line) {
	$content .= trim($line)."\n";
}
$content = preg_replace("#[\\r\\n]{3,}#s","\n\n",$content);
