+* @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.
