使cookie在3或5秒后过期

Question

I need a cookie on my site just for a few seconds. What i tried is this:

$value = 12;
$cookie = setcookie("myCookie", $value, time() + 3);

The cookie gets created, but needs longer to expire than 3 seconds

Answer 1

Very simple time math here.

$value = 12;

$seconds_in_seconds = 1;
$minute_in_seconds = 60
$hour_in_seconds = 60 * 60;
$day_in_seconds = 60 * 60 * 24
$week_in_seconds = 60 * 60 * 24 * 7
  /*ect...*/
/*60 seconds in a minute. Times 2 minutes plus 10 seconds. Makes 2 minutes and ten seconds.*/
$time = time() + (2 * $minute_in_seconds) + (10 * $seconds)
$cookie = setcookie("myCookie", $value, $time);
