How to add emoji to the database?

Question

css

It is necessary to add text containing emoji emoticons to the database.
I tried this:

$str='<p>Текст с emoji. Еще текст</p>'; //Вместо emoji должен быть смайл
$res = $db->prepare("INSERT INTO `table` (`str`) VALUES (:str)");
$res->bindParam(":str", $str, PDO::PARAM_STR, 60);
$res->execute(); //В базе сохранится строка "<p>Текст с "

But the line is truncated. Only the text up to emoji is entered into the database. I tried to process the string with htmlentities();, but there is no result. Emoji remain untouched.
Encoding utf-8 if that matters.
Please tell me how to solve the problem

Answer 1

You can add this image with :before, give absolute positioning like the black checkbox, and give the image a z-index greater than the checkbox.
Then the picture will be on top of the black flag

Answer 2

You cannot make an image that goes beyond the block using the background. Only to have a separate element, and to position.

Answer 3
