A Cookie is usually accustomed established a user. A cookie
could be a little file that server embeds on the user’s PC. Each time
a similar PC request a page with a browser,it will send a cookie too.
With a PHP, you’ll each produce and receive cookie’s value.
Syntax of cookie is:
setcookie(name, values, expiry, path, domain);
We take a example which makes easier to understand this:
- Setcookie( ) function is used to set cookie.
- Setcookie() function must appear before the <html> tag.
Syntax of cookie is:
setcookie(name, values, expiry, path, domain);
We take a example which makes easier to understand this:
| HTTP/1.1 200 OK Date: Fri, 25 Jan 2005 18:15:05 GMT Set-Cookie:name=joy;expires=Sunday,25-Jan-09 10:33:45 GMT; path=/; domain=fullyhelp.com |
Retrieving a cookie:
PHP $_cookie variable is used to retrieve a cookie value.| <?php // Print a cookie echo $_COOKIE[“joy”]; // The technique is used to view all cookies print_r($_COOKIE); ?> |
Delete a Cookie:
Deleting a php cookies is very simple process, set the value of the cookie to null, and also set the expire time of the cookie in the past. Ideally, one would set the expiry time to about a year in the past, so that if the system time is off , then the cookie will still delete correctly.| <?php // set the expiration date to one year ago setcookie(“name”, “”, time()-365); ?> |
