        <b>Hello to everyone</b>

//calling the remove_html_tags function with the necessary html tags you want to remove
$removed_str=remove_html_tags($html_string, array("html", "body", "span","b"));

//To avoid executing rest tags it is converted to normal text and display the result
echo htmlentities($removed_str);

function remove_html_tags($html_string, $html_tags) 
    $tagStr = "";
        foreach($html_tags as $key => $value) 
            $tagStr .= $key == count($html_tags)-1 ? $value : "{$value}|"; 
    $pat_str= array("/(<\s*\b({$tagStr})\b[^>]*>)/i", "/(<\/\s*\b({$tagStr})\b\s*>)/i");
