The setcookie() function sends Cookie
bool setcookie ( string $name [, string $value="" [, int $expire=0 [, string $path="" [, string $domain="" [, bool $secure=false [,bool $httponly=false]]]]]] )
It is used to set COOKIES.
The setcookie() function sends the Cookie once it is defined, along with the remaining HTTP headers to the client. Like other HTTP headers, the Cookie must be sent before any output is generated by the script (due to protocol restrictions). Please call this function before generating any output (including <html> and <head> or spaces).
Once the Cookie is set, it can be read using $_COOKIE when the page is opened next time. The Cookie value also exists in $_REQUEST.
If output has been produced before calling this function, setcookie() will fail and return FALSE. If setcookie() runs successfully, it returns TRUE. Of course, this does not mean that the user has accepted the Cookie.
