[PHP] setcookie problem: Cannot add header information - headers already sent by
here is the example:
Feedback form
Feedback form
ENDH;
// End of page header
// Saving the page footer in the variable $tail.
$tail = <<
ENDT;
// End of page footer
// Set up variables that will be saved in the cookies
// Define unique cookie prefix
$ID = "My_ID";
// Cookie lifetime in seconds (in this example, three days)
$cookie_life = 60;
// Name of cookie that holds the user's name
$n_name = $ID . "_Name";
// Name of cookie that holds the user's email
$n_email = $ID . "_Email";
// Name of cookie that holds the user's last login
$n_last = $ID . "_Last";
// These lines print the form with user input and mails to the
webmaster.
if( isset($sfeedback)) {
Setcookie($n_last,Date("H:i d/m/Y"),time()+$cookie_life);
print $head;
?>

RE: [PHP] setcookie problem
this is my guess at what's happening... i dont know
100% if that's why cookies aren't setting properly,
but here's an educated guess on my part:
probably becuase time() is seconds since 1970, and as
far as i understand, once it gets over 999,999,999
it will not work correctly becuase it will roll over
(similar to the Y2k bug) and become 000,000,000
for example:
00,900,000,000 - current time (for example)
36,000,000,000 - what you're trying to add
--
36,900,000,000 - result
but the buffer is only big enough for 999,999,999
and so the computer truncates the leading "36"
and leaves you with 900,000,000 (which was the exact
time that you set the cookie, making it expire as
soon as you set it)
instead of adding such wildly huge numbers, try
adding 1-2 years...
besides, it's kind of scary to think that your cookies
might outlive you, if that timestamp was really acceptable :)

[PHP] setcookie problem
Hi,
How to set a forever cookie into client machine. I use the following
syntax to set the cookie, but when I close the brower's window, then the
cookie is deleted when the browser closed.
setcookie("buyerid",$email,time()+360,"","$domain");
setcookie("buyeridpasswd",$passwd,time()+360,"","$domain");
Thank you for your attentions,
Mark Lo
