Please PHP cookies are a mechanism to store small amount of data via browser on a user computer, usually used for permanent login to websites like Facebook, Twitter, for online shopping etc.
In PHP there are 2 functions for creating a cookie - setcookie() and setrawcookie(). The complete syntax of the setcookie function is
bool setcookie ( string $name [, string $value [, int $expire = 0 [, string $path [, string $domain [, bool $secure = false [, bool $httponly = false ]]]]]] )
The only required parameter is $name, that is the name of the cookie, all other parameters are optional. For example if you want to store the time of the page loading, you can write
setcookie('loaded_time', date('r'));
and if you want to display the cookie content to the browser, you can write
echo $_COOKIE['loaded_time'];
To make the cookie persistent, you must set the third parameter $expire to a long period, for example 3600x24x365 is 1 year, because $expire contains time in seconds:
setcookie('loaded_time', date('r'), time()+3600*24*365);
The function time() returns the number of seconds since January 1, 1970, so this sets the expiration of the cookie to the next year.
The function setrawcookie() does the same, but without urlencoding the cookie value, its syntax is:
bool setrawcookie ( string $name [, string $value [, int $expire = 0 [, string $path [, string $domain [, bool $secure = false [, bool $httponly = false ]]]]]] )

How do you create a cookie and where will it placed in php?
You can set a cookie using the setcookie() function. You can do this as many times as you wish during your script. Remember that the cookie will not be available to PHP until the next time the page is loaded (or the script is called by a new HTTP request). On the next page, you can access the cookie data from the $_COOKIE super-global array. The key will be the name of the cookie, and the value will be the value you assigned to it the last time you set it.
