Cookie implementation in php

: This article mainly introduces the implementation of cookies in php. For more information about PHP tutorials, see. Cookie implementation

Cookie is different from session. a session can be used as long as it is uploaded to the server and as long as it is on the webpage. However, if the cookie is not set, it can only be used in the current path.

Cookie has five attributes: setcookie ("name", value, time, path, domain ).

To use the path on other pages, you must perform operations on the path. if you use "/" instead of "path", you can use the path on the whole page.

You need to perform operations on time () when defining the time, for example

Setcookie ("name", value, time () + 3600 );

This means that the cookie is saved for one hour. After one hour, the webpage will automatically cancel the cookie;

$ _ Cookie ("name"); is used to retrieve COOKIE data.

Delete cookie

There are two methods to remove cookies: setcookie ("name"); reset the time to 0; setcookie ("name", value, 0 );
