I have string:
Verslo centrai Lietuvos nekilnojamojo turto plėtros asociacijos konkurse ...
Try to put it like that
$content = strip_tags($text);
Or you can do it with regular expression like that:
$content = preg_replace('/<[^>]*>/', '', $text);
By this ');$content = strip_tags($text, '
you are allowing the tag in the string.
