View source for Cookies/Setting A Cookie/PHP (Server Side)

{{quote|Note that, since cookies are set in the HTTP headers, they shall be set before the HTML (or whatever you transmit over [[HTTP]]) output starts.|Savitri}}

See [http://php.net/manual/en/function.setcookie.php PHP.net]. Basically, 

{{code | text=<syntaxhighlight lang="php">
//setcookie ( string $name [, string $value [, int $expire = 0 [, string $path [, string $domain [, bool $secure = false [, bool $httponly = false ]]]]]] )

setcookie('my_lover', 'hero hitler (or was it Mr. #?)', time()+1800, '/', '.staff.blackhatacademy.org', false, false); // the false, false at the end is not mandatory, since these parameters are marked as optional.
// $value is to be set to the desired value. Note that you shall not use booleans, as setting $value to false will delete the cookie
// $expire is the timestamp at which this cookie shall expire
// $domain sets the Domain flag (see [[#Flags|Flags section]]
// $secure sets the Secure flag (see [[#Flags|Flags section]]
// $httponly sets the HttpOnly flag (see [[#Flags|Flags section]]
</syntaxhighlight>}}
