Is it safe to store data in session PHP?
So, by default, data there is as safe as your server is. If your server is compromised, then confidential info in session data is the least of your problems. There is no point in storing passwords in the session. So, safe or not safe – it doesn’t matter at all (however it is obviously not safe).
What should I store in PHP session?
A PHP session stores data on the server rather than user’s computer. In a session based environment, every user is identified through a unique number called session identifier or SID. This unique session ID is used to link each user with their own information on the server like emails, posts, etc.
Where does PHP session get stored?
PHP Default Session Storage (File System): In PHP, by default session data is stored in files on the server. Each file is named after a cookie that is stored on the client computer. This session cookie (PHPSESSID) presumably survives on the client side until all windows of the browser are closed.
Where is PHP $_ session stored?
By default, session data is stored in the server’s /tmp directory in files that are named sess_ followed by a unique alphanumeric string (the session identifier).
Is it safe to store the database password in a PHP file?
There is an additional risk with storing passwords in a .php file within your webroot, which is a bit obscure but can be easily avoided by placing the file outside of your web root.
How are PHP sessions secure to the user?
PHP sessions are only secure as your application makes them. PHP sessions will give the user a pseudorandom string (“session ID”) for them to identify themselves with, but if that string is intercepted by an attacker, the attacker can pretend to be that user.
So, in short: PHP sessions are as secure, as your use of them makes them be. This is true for any session-cookie-based system I know of. Is this answer outdated?
Where are PHP session IDs stored in Apache?
It should be noted that in Apache the PHP $_SESSION superglobal is accessible across virtualhosts. Consider this scenario: Your server hosts two domains, example.com and instance.org. PHP sessions are stored in cookies that are restricted to the domain. A user logs in to example.com and receives a session ID.
