setcookie(“user”, “”, time()-3600) not working

Question

I tried to use setcookie("user", "", time()-3600) to delete a cookie from php, but it's not working for me, when I check in the tool of the broswer, the cookie seems to still exist. Does anyone know why?

note: this is the domain cookies.. mean I set this cookies with this way setcookie('user','true',time() + 2592000,"/",".user.com",0);

Answer 1

Try setcookie ('user', "", time() - 3600, "/", ".user.com", 1);
Just a warning- IE and opera sometimes maintain cookie values until after restart- that may be part of the issue.

Answer 2

setcookie("user", 0, time()-3600)

Answer 3

根据PHP文档 ，您的代码应该可以正常运行，但是，您可以尝试以下操作：

setcookie("user", "", time() - 3600, "/", ".user.com", 0);
