声明
<?php register_sidebars( $number, $args ); ?>
建立多个侧边栏（工具条）。
注册一个或多个侧边栏在当前主题中使用。多数主题只有一个侧边栏。由于以上原因，参数number是可选择的并且默认值是1。
args数组可以包含一系列侧边栏的名字，如果有多于一个的侧边栏。如果没有定义名字，默认使用’Sidebar’。
参数
$number
(int) (必需的) 要建立的侧边栏的数量。
$args
(string/array) (必需的) 建立基于名字和’id’的边栏。
例子
下面这个例子将会建立一个侧边栏，名为Sidebar：
register_sidebars();
下面这个例子将会建立两个侧边栏，名为“Foobar 1″和“Foobar 2″：
register_sidebars(2, array(‘name’=>’Foobar %d’));

源文件
register_sidebars()位于wp-includes/widgets.php。
/**
* Creates multiple sidebars.
*
* If you wanted to quickly create multiple sidebars for a theme or internally.
* This function will allow you to do so. If you don’t pass the ‘name’ and/or
* ‘id’ in $args, then they will be built for you.
*
* The default for the name is “Sidebar #”, with ‘#’ being replaced with the
* number the sidebar is currently when greater than one. If first sidebar, the
* name will be just “Sidebar”. The default for id is “sidebar-” followed by the
* number the sidebar creation is currently at.
*
* @since 2.2.0
*
* @see register_sidebar() The second parameter is documented by register_sidebar() and is the same here.
* @uses parse_str() Converts a string to an array to be used in the rest of the function.
* @uses register_sidebar() Sends single sidebar information [name, id] to this
* function to handle building the sidebar.
*
* @param int $number Number of sidebars to create.
* @param string|array $args Builds Sidebar based off of ‘name’ and ‘id’ values.
