<b>setcookie() </b>is the main function that is used to work with cookiesin PHP<br>
<br>
parameters are as follows:<br>
<br>
setcookie (string name , string value , int expire , string path , string domain
, int secure)<br>
<br>
<br>
Cookies are sent to the user's computer thru the header: in static files, because
this is the case you must set, expire your cookies before displaying anything
thru your script.. before any echo() and/or print() functions. This is not a PHP
setback, it the way HTML works :o) Check out this simple function i have written.
