script tag inside block?

Question

PHP

Hello everyone, I have a question.
I have a string in a div tag and it contains a script tag (as plain text). But the browser recognizes it as a tag and puts everything after it inside the tag. Tell me how to fix this)
You can use php and js, but I would like to find a solution without them)

Answer 1

Escape HTML special characters:
php.net/manual/ru/function.htmlspecialchars.php

echo htmlspecialchars('<script>...</script>', ENT_QUOTES); 
// &lt;script&gt;...&lt;/script&gt;

Answer 2

$text = $_POST["comment"];
echo htmlspecialchars($text);//can also return htmlspecialchars($text);
