setting and deleting cookies

[laredotornado]

Hi,

I'm using PHP 4.4.4 on Fedora Core 5 Linux. Two questions, if I
create a cookie under the "/" path ...

setcookie('LoggedIn', 1, time() + REMEMBER_ME_TIME, "/");

1. How do I check if this cookie is set at the top of a given PHP
page?

2. How do I delete this cookie?

Thanks for your help, - Dave

Go to the next page and try to echo it... yes, the NEXT page:

<?php
$LoggedInCookie = $_COOKIE['LoggedIn'];
echo $LoggedInCookie;
?>

2. How do I delete this cookie?

set it again with negative time:

setcookie("LoggedIn", '', time()-42000, '/'); //erase the cookie
good luck!

if (isset($_COOKIE['LoggedIn']))
echo "Cookie is set.";

Re-set the cookie, using a time in the past.

setcookie('LoggedIn', 0, 0, "/");

By the way, if this is for a log in system, it's hideously insecure. Users
can easily tamper with cookies. Use sessions instead.
