Keskustelu: Koodit: PHP Menu

<?php

	/*
	 *  Menu script is coded by Joni Järvinen a.k.a Jope <jope@psykoosi.org>
	 *  More scripts can be found at http://jope.psykoosi.org/ (Finnish site)
	 *
	 *  With this script you can easily create menu simply by creating an array
	 *  in form which you can see in example at the end of function
	 *
	 *  Then use function to create menu:
	 *    MakeMenu (Array menu, String menu_name [, String pos [, String intend]])
	 *
	 *  You can create as many menus as you want, but you must give name for
	 *  every menu.
	 *
	 *  There may be coming function for this functon so you can create
	 *  menu array easily from directory: $menu = MakeArray("/path/to/menu/folder");
	 *  And then you can use $menu like this: echo MakeMenu($menu, "id");
	 *
	 */

Example (Try this!):

	/*
	 *  Every index means menu item. Every index includes array which
	 *  has 2 to 4 values. First value indicates weather we add
	 *  query string at the end of address or not. 1 means not and 0
	 *  means yes.
	 *
	 *  Second value indicates address for example "http://jope.psykoosi.org/"
	 *  In this example we leave it empty.
	 *
	 *  Third one is your own query string after menus own. Do NOT add
	 *  ? or & before the query string.
	 *
	 *  Fourth one is optional and if it is set it must be array and that
	 *  indicates that this menu item has subitems.
	 *
