I would like to buy brendanr@optushome.com.au a beer or three!
Thanks to his example above (26-Feb-2002 11:42) I finally managed to get things straight in my head.
The difficulty was not necessarily in setting a cookie - there are copious examples on how to do
that! - but more with reading cookies! With his example, I was able to change $vars, play with
settings and find out how all this fitted together!
I love you!
If the following 'simpleton' example will at least go half way to helping someone else,
the all the better!
#!/usr/local/bin/php (my server requires php files to be run as a script, similar to a PERL CGI
for example. If yours doesn't, just delete this first line and I think it should work!)
<?
$lang=strtok($_SERVER["HTTP_ACCEPT_LANGUAGE"],',');
//my site is multi-linguag, therefore I'd like to know the client's language setting
if(empty($HTTP_COOKIE_VARS['user_name'])) {
// set cookie and store the creation time within the value of the cookie
//I've places a few $vars here and there as on-screen displays, so you can see what's
happening!
$cookie_var1 .= "HTTP_COOKIE_VARS[user_name] IS EMPTY : CREATING COOKIE : ";
setcookie("user_name",
"meetn2veg"."|"."$lang"."|".time(),3600);
$cookie_var1 .= "COOKIE CREATED<BR>";
} else {
// check if cookie has expired, if so delete it
$cookie_life = 3600;
$cookie_info = explode("|", $HTTP_COOKIE_VARS["user_name"]);
$cookie_user = $cookie_info[0];
$cookie_lang = $cookie_info[1];
$cookie_time = $cookie_info[2];
$life_left = $cookie_life - (time()-$cookie_time);
if((time()-$cookie_time) > $cookie_life) {
// cookie has expired so delete it.
$cookie_var1 .= "COOKIE EXPIRED : ";
setcookie("user_name", "");
$cookie_var1 .= "COOKIE DELETED<BR>";
} else {
$cookie_var1 .= "COOKIE STILL ALIVE! COOKIE HAS $life_left seconds to live!<BR>";
}
}

Just place this in one file, if server requires php files to be run as scripts, leave the first lin
( #!/usr/local/bin/php ), changing to suit your servers' config and chmod 755, look at it from
a browser and just keep pressing F5 !!!! Change a few settings, upload and F5 again to see what
happens.
I can't say it works on all flavours, all browsers, at this precise moment, I don't care!
It works for me! And after 3 weeks on and off trying to suss this one out, I'm chuffed to
bits!
Hope it helps someone else.
