How to Create Login Form With Session in PHP How to create login form with session in php - Session is quite important in web based applications. Sessions allow the programmer to store user information semi-permanently, meaning that during certain periods information is stored. Storage of the contents of the session variable resides on the server, so it can not be accessed directly by the client. In web-based applications, sessions are widely used as login authentication. Sessions allow the programmer to manage who can access a page. For example, to see the mailbox page in the email, we must login first. In the login process among others will occur making a session that will be brought by the user on each page. On the mailbox page, the session will be checked. If the session is correct then the user is welcome to open the mailbox page, but if wrong then the user can not open the mailbox page and usually will be prompted to login first. That is, the user can not access the mailbox page directly without logging in. In the session handling there are several processes that need to be considered:
Session creation process Session inspection process Session removal process
Next how the session itself is run? In order for the storage process in the session to run, PHP does the following: 1. PHP generates an ID session. This session ID is a random number of random numbers for each user and almost impossible to guess. The session ID is stored by PHP inside the PHP system variable named PHPSESSID 2.PHP stores the value you want to store in a session inside a file located on the server. The filename for the session storage matches (same) with the session ID. Files are stored in a directory indicated by session.save_path in the php.ini file. 3. PHP throws an ID session into every page. 4. PHP retrieves session values from session files for each session page. Here is an example of a program to create login form using session in php.
