note 123567 added to function.setcookie

I haven't seen this mentioned here and had a lot of issues (and created a lot of stupid hacks) before I figured this out. If you have a couple of environments for example, and are trying to set cookies on two domains: example.com (main site) dev.example.com (dev site) In this case your (same named) cookies will interfere with each other if you're trying to set cookies with the domain parameter. Simply use an empty string for the domain parameter and the cookies will refer to each host separately. If you use the subdomain www. on the main site this won't be an issue, but without a subdomain you'll have issues with reading each others' cookies. ---- Server IP: 208.43.231.9 Probable Submitter: 82.199.157.35 (proxied: 68.3.207.202) ---- Manual Page -- http://php.net/manual/en/function.setcookie.php Edit -- https://master.php.net/note/edit/123567 Del: integrated -- https://master.php.net/note/delete/123567/integrated Del: useless -- https://master.php.net/note/delete/123567/useless Del: bad code -- https://master.php.net/note/delete/123567/bad+code Del: spam -- https://master.php.net/note/delete/123567/spam Del: non-english -- https://master.php.net/note/delete/123567/non-english Del: in docs -- https://master.php.net/note/delete/123567/in+docs Del: other reasons-- https://master.php.net/note/delete/123567 Reject -- https://master.php.net/note/reject/123567 Search -- https://master.php.net/manage/user-notes.php
