$myHtml = // here is your html;
$doc = new DOMDocument();
$doc->loadHTML($myHtml);
removeElementsByTagName('script', $doc);
removeElementsByTagName('style', $doc);
$html = $doc->saveHtml();
function removeElementsByTagName($tagName, $document) {
$nodeList = $document->getElementsByTagName($tagName);
for ($nodeIdx = $nodeList->length; --$nodeIdx >= 0; ) {
$node = $nodeList->item($nodeIdx);
$node->parentNode->removeChild($node);
}
}

Few alternatives to CKEditor. Check if they work for you.
