Bug #14571 Updated: setcookie behavoir changed in 4.1 from previous versions

ID: 14571 Updated by: derick Reported By: smclean@scoreinfo.tv Status: Bogus Bug Type: Documentation problem Operating System: Linux PHP Version: 4.1.0 New Comment: From the manual: (http://uk.php.net/manual/en/function.setcookie.php) Some examples follow how to send cookies: Example 1. setcookie() send examples a. setcookie ("TestCookie", "Test Value"); b. setcookie ("TestCookie", $value,time()+3600); /* expire in 1 hour */ c. setcookie ("TestCookie", $value,time()+3600, "/~rasmus/", ".utoronto.ca", 1); Examples follow how to delete cookies send in previous example: Example 2. setcookie() delete examples a. setcookie ("TestCookie"); // set the expiration date to one hour ago b. setcookie ("TestCookie", "", time() - 3600); c. setcookie ("TestCookie", "", time() - 3600, "/~rasmus/", ".utoronto.ca", 1); When deleting a cookie you should assure that the expiration date is in the past, to trigger the removal mechanism in your browser. Previous Comments: ------------------------------------------------------------------------ [2001-12-18 03:48:17] sander@php.net This hasn't changed. setcookie('name','') doesn't remove the cookie, and it never did. To remove a cookie, use setcookie with a expire-date in the past, i.e. setcookie('name','', time()-10000). ------------------------------------------------------------------------ [2001-12-17 21:36:35] smclean@scoreinfo.tv The behavoir of the setcookie function changed in 4.1.0 even though no such change was documented in the changelog. This had the effect of disabling an application of mine until I figured out what happened. In PHP <4.1.0, the code: setcookie("cookiename",""); would delete the cookie 'cookiename'. In PHP 4.1.0, this function created a cookie with a null value named cookiename. I know this is a rather silly change, and you wouldn't expect someone to ever specify a blank value in the second argument, but it did cause a short downtime in our website software. I posted this on the setcookie() manual page but it was rejected on grounds that it was more of a bug report than anything, so I thought I'd post it here.
