-* See {@link \phpbb\request\request_interface::variable \phpbb\request\request_interface::variable} for

-* documentation of this function's use.

-*

-* @deprecated

-* @param mixed $var_name The form variable's name from which data shall be retrieved.

-* If the value is an array this may be an array of indizes which will give

-* direct access to a value at any depth. E.g. if the value of "var" is array(1 => "a")

-* then specifying array("var", 1) as the name will return "a".

-* If you pass an instance of {@link \phpbb\request\request_interface phpbb_request_interface}

-* as this parameter it will overwrite the current request class instance. If you do

-* not do so, it will create its own instance (but leave superglobals enabled).

-* @param mixed $default A default value that is returned if the variable was not set.

-* This function will always return a value of the same type as the default.

-* @param bool $multibyte If $default is a string this paramater has to be true if the variable may contain any UTF-8 characters

-* Default is false, causing all bytes outside the ASCII range (0-127) to be replaced with question marks

-* @param bool $cookie This param is mapped to \phpbb\request\request_interface::COOKIE as the last param for

-* \phpbb\request\request_interface::variable for backwards compatability reasons.

-* @param \phpbb\request\request_interface|null|false If an instance of \phpbb\request\request_interface is given the instance is stored in

-* a static variable and used for all further calls where this parameters is null. Until

-* the function is called with an instance it automatically creates a new \phpbb\request\request

-* instance on every call. By passing false this per-call instantiation can be restored

-* after having passed in a \phpbb\request\request_interface instance.

-*

-* @return mixed The value of $_REQUEST[$var_name] run through {@link set_var set_var} to ensure that the type is the

-* the same as that of $default. If the variable is not set $default is returned.
