You want to read the value of a cookie that you’ve previously set.
Look in the $_COOKIE superglobal array:
|
1 2 3 |
if (isset($_COOKIE['flavor'])) { print "You ate a {$_COOKIE['flavor']} cookie."; } |
A cookie’s value isn’t available in $_COOKIE during the request in which the cookie is set. In other words, calling the setcookie() function doesn’t alter the value of $_COOKIE.
On subsequent requests, however, each cookie sent back to the server is stored in $_COOKIE.
When a browser sends a cookie back to the server, it sends only the value. You can’t access the cookie’s domain, path, expiration time, or secure status through $_COOKIE because the browser doesn’t send that to the server.
To print the names and values of all cookies sent in a particular request, loop through the $_COOKIE array:
|
1 2 3 |
foreach ($_COOKIE as $cookie_name => $cookie_value) { print "$cookie_name = $cookie_value <br/>"; } |
