For some reason, and I've not noticed this before,

setcookie("<cookiename>","<somevalue>"); 

works fine,

but after that, if you wish to clear the cookie wich was set with:
setcookie("<cookiename>");

doesn't work anymore, thus leaving the cookie present until it expires (in this case when the browser is closed)

is this a bug or something that is only misbehaving on my system?

Cheers,
Arjan

setcookie("test"); 

Deletes the cookie like it should in my system. 
Are you trying to set and delete the cookie in same script?
The order in which this should be done is different in php3 and php4.

Reset type to Documentation Problem. There isn't anything about deleting cookies
in the manual section for setcookie function.

When cookies are set with the optional parameters, those parameters must be
used also when the cookie is deleted.

read thoroughly...

taken from setcookie() doc:
[...]
All the arguments except the name argument are optional. If
only the name argument is present, the cookie by that name
will be deleted from the remote client
[...]

reporter, please respond to entry "[2000-08-15 11:08:17]

Probably my mistake not to inform this bug report that user knows this. 
It was me who analyzed and confirmed that the setcookie() documentation
misses some information about deleting cookies. 

And the function prototype there is wrong too. 
It says that all the parameters are needed..

If cookie is set with one or more of the optional parameters, it has to be 
deleted with the same parameters. 

So this is documentation problem which I (if someone doesn't get to it first) will
fix when I have time.
