1. Cookie

1. How to get the value in cookie?

Example jumps to a.php through index.php to get the corresponding value jason with the key name;

index.php code:

        

         Copy after login
        
       

        

         Copy after login
        
       

2. How to access cookies through javascript?

3. If the browser or user has disabled cookies, how to pass parameters between pages?

Example passes the value of b.php to c.php through URL parameters;

b.php code:

        

         Copy after login
        
       

        

         Copy after login
        
       

二.session:

1. Each time the browser is reopened, the server will assign a new session_id value to the client.

        

         Copy after login
        
       

Example jumps to a.php through index.php to display the value corresponding to the corresponding key of the session:

index.php code;

        

         Copy after login
        
       

        

         Copy after login
        
       

3. What should I do if I want to destroy the session? (ps application scenario: clear login status after timeout)

PHP provides session_destroy() to destroy the session.

Insertsession_destroy() in index.php:

        

         Copy after login
        
       

The above introduces the session management of PHP, including various aspects. I hope it will be helpful to friends who are interested in PHP tutorials.
