如何在函数中重复数组以使用foreach

Question

这很好用，但这对我来说很傻，因为我甚至不知道要搜索什么（或者问题的标题是否正确），以了解如何完成不重复$slide_panels数组低于它的christina_slide_in_panels()函数及其外部。

可悲的是，这个问题已经结束，但史蒂夫的回答是在评论中。通过阅读“重复”的接受后答案回答问题没有回答，至少没有具体说明。

//* register slide panels

$slide_panels = array (
            'slide-1'       => 'Slide Panel One',
            'slide-2'       => 'Slide Panel Two',
            'slide-3'       => 'Slide Panel Three',
            'slide-4'       => 'Slide Panel Four',
            );


foreach ( $slide_panels as $id => $slide_panel) {
    register_sidebar(
        array (
                'name'          => __( $slide_panel, 'christina' ),
                'id'            => $id,
                'before_widget' => '<aside id="%1$s" class="slide-widget %2$s">',
                'after_widget'  => '</aside>',
                'before_title'  => '<h3 class="slide-widget-title">',
                'after_title'   => '</h3>',
        ));

}


//* create the panels

function christina_slide_in_panels() {

   //======== > HOW TO NOT REPEAT THIS < ========
   $slide_panels = array (
            'slide-1'       => 'Slide Panel One',
            'slide-2'       => 'Slide Panel Two',
            'slide-3'       => 'Slide Panel Three',
            'slide-4'       => 'Slide Panel Four',
            );  

    echo '<!-- begin slide panels --><div class="slide-in-panels-parent">';

    foreach ( $slide_panels as $id => $slide_panel) {

        if ( is_active_sidebar( $id ) ) {

            echo '<div class="slide-panel" id="'.$id.'" aria-expanded="false" aria-hidden="true">';
            // id used on the toggle to get this slide in

            dynamic_sidebar( $id );

            echo '</div><!-- close '.$id.' -->';
        }
        //end endif;
    }
    //end foreach

    echo '</div><!-- end slide panels -->';
    //close parent;


}
add_action('genesis_after', 'christina_slide_in_panels');
