The difference between php session and cookie_PHP tutorial

The difference between cookie and session in php:

1. Cookie data is stored on the customer's browser, and session data is placed on the server.

2. Cookies are not very safe. Others can analyze the cookies stored locally and deceive them. Sessions should be used for security reasons.

3. The session will be saved on the server within a certain period of time. When access increases, it will take up more of your server's performance. In order to reduce server performance, COOKIE should be used.

4. The limit of a single cookie on the client is 3K, which means that a website cannot store 3K COOKIES on the client.

So personal suggestion: Store important information such as login information as SESSION. If other information needs to be retained, it can be placed in COOKIE .
