note 71591 added to function.setcookie

Note when setting "array cookies" that a separate cookie is set for each element of the array. On high traffic sites, this can substantially increase the size of subsequent HTTP requests from clients (including requests for static content on the same domain). More importantly though, the cookie specification says that browsers need only accept 20 cookies per domain. This limit is increased to 50 by Firefox, and to 30 by Opera, but IE6 and IE7 enforce the limit of 20 cookie per domain. Any cookies beyond this limit will either knock out an older cookie or be ignored/rejected by the browser. ---- Server IP: 203.16.234.90 Probable Submitter: 218.214.21.210 ---- Manual Page -- http://www.php.net/manual/en/function.setcookie.php Edit -- https://master.php.net/note/edit/71591 Del: integrated -- https://master.php.net/note/delete/71591/integrated Del: useless -- https://master.php.net/note/delete/71591/useless Del: bad code -- https://master.php.net/note/delete/71591/bad+code Del: spam -- https://master.php.net/note/delete/71591/spam Del: non-english -- https://master.php.net/note/delete/71591/non-english Del: in docs -- https://master.php.net/note/delete/71591/in+docs Del: other reasons-- https://master.php.net/note/delete/71591 Reject -- https://master.php.net/note/reject/71591 Search -- https://master.php.net/manage/user-notes.php
