Does a session variable($_SESSION) require any type of sanitiziation


Does a session variable($_SESSION) require any type of sanitiziation

To fix this issue Variables in session are not vulnerable to attacks within the session. However, using those variables in other places may open up holes. For example, just because you put a get/post variable in session doesn't mean that it magically can be used directly in a query. It could still cause SQL injection issues. When considering stuff like this, you have to think about where the data originated. If it started from some sort of user input, consider it dirty.
The only place this might be a problem is if the data sent is really large and you are just blindly assigning $_SESSION['POST'] = $_POST;. There shouldn't be an issue with overflow or stuff like that. The problem will be more that php has to unserialize the data at the start of a request and reserialize at the end (typically only if a change has happened). This unserialize/serialize takes time (it may be quick, but still). I would suggest just assigning only the values you want to save.

I wish this helpful for you It's unnecessary and will have no effect.
If you are calling sensitive data through Ajax calls, you need to properly secure it against attacks, just as you would secure a normal page - for example by having a session-based login, and checking whether the current user is logged in!

hop of those help? count() returns long and not every long can fit into an int hence an explicit cast is required to store the result into an int. This is nothing to do with java-10. it's always been there in previous JDK's.
If you don't want to cast then the alternative would be:
code :
...
.filter(n -> n < 0)
.map(e -> 1)
.sum();

To fix this issue Put your session_start(); at the very top of your code, for example, at the very top of your final.php file rather than in your process.php file.
E.g.;
code :
<?php
    session_start();
    include 'database.php'; 
?>
