    Hello Reader's If you want to make an function which truncate all the html contents and ignore them then you can uset the Sren Lvborg printTruncated function making it UTF-8 (Needs mbstring) function. It's example as below:-

    /* Truncate HTML, close opened tags
    *
    * @param int, maxlength of the string
    * @param string, html 
    * @return $html
    */
    
    function htmlTruncate($maxLength, $html)
    {
        mb_internal_encoding("UTF-8");
        $printedLength = 0;
        $position = 0;
        $tags = array();
        $out = "";

    while ($printedLength < $maxLength _ mb_preg_match('{</?([a-z]+)[^>]*>|_[a-zA-Z0-9]+;}', $html, $match, PREG_OFFSET_CAPTURE, $position)) { list($tag, $tagPosition) = $match[0];

    // Print text leading up to the tag. $str = mb_substr($html, $position, $tagPosition - $position); if ($printedLength + mb_strlen($str) > $maxLength) { $out .= mb_substr($str, 0, $maxLength - $printedLength); $printedLength = $maxLength; break; }

    $out .= $str; $printedLength += mb_strlen($str);

    if ($tag[0] == '&') { // Handle the entity. $out .= $tag; $printedLength++; } else { // Handle the tag. $tagName = $match[1][0]; if ($tag[1] == '/') { // This is a closing tag.

    $openingTag = array_pop($tags); assert($openingTag == $tagName); // check that tags are properly nested.

    $out .= $tag; } else if ($tag[mb_strlen($tag) - 2] == '/') { // Self-closing tag. $out .= $tag; } else { // Opening tag. $out .= $tag; $tags[] = $tagName; } }

    // Continue after the tag. $position = $tagPosition + mb_strlen($tag)
