Correct way to set/remove cookie?

Hi everyone,
I just want to know, would the following code work for setting a raw array cookie:

setrawcookie("userinfo[username]", $username, time()+60*60*24*21, "/", TRUE, TRUE);
setrawcookie("userinfo[password]", $password, time()+60*60*24*21, "/", TRUE, TRUE);

PHP:

and this code for removing it?

if (isset($_COOKIE["userinfo"]))
{
setrawcookie("userinfo[username]", $username, time()-60, "/", TRUE, TRUE);
setrawcookie("userinfo[password]", $password, time()-60, "/", TRUE, TRUE);
}

PHP:

Thanks in advance.

 

Everything looks good. On a side note, unsetting the cookie by calling a past date is correct, but I would use/set a blank value "" instead of the variables you're using.

 

so like this for setting it

setrawcookie("userinfo[username]", $username, time()+60*60*24*21, "/", TRUE, TRUE);
setrawcookie("userinfo[password]", $password, time()+60*60*24*21, "/", TRUE, TRUE);

PHP:

but like this for removing it?

if (isset($_COOKIE["userinfo"]))
{
setrawcookie("userinfo[username]", "", time()-60);
setrawcookie("userinfo[password]", "", time()-60);
}

PHP:

 

not removing all is good
