php获取数组的名称

Question

$shortcodes['video_section'] = array(
    'no_preview' => true,
    'params' => 'xxx',
    'shortcode' => '[sc1][/sc1]',
    'popup_title' => __('Video Section', THEME_NAME),
    'shortcode_icon' => __('li_video')
);

$shortcodes['image_section'] = array(
    'no_preview' => true,
    'params' => 'yyy',
    'shortcode' => '[sc2][/sc2]',
    'popup_title' => __('Image Section', THEME_NAME),
    'shortcode_icon' => __('li_image')
);

$shortcodes[] = $th_shortcodes;

How can I retrieve the name of each array and then access to the key and value:

for example I need to loop throught $shortcode and get the array main name: 'image_section' 'video_section'

Then to retrieve the value of some key. I know how to retrieve key and value but really don't understand how to get the name of the declared array. If i do: var_dump($value); I saw the name of the array but how to access to it?

Answer 1

You can use foreach

foreach($shortcodes as $key => $value) {
  echo $key // echoes "vide_section" and "image_section" 

  foreach($value as $innerKey => $innerValue) {
    echo $innerKey // echoes 'no_preview', 'params', 'shortcode', 'popup_title', 'shortcode_icon' twice
  }
}

Note that $value in this case refers to arrays, you can foreach again to access the inner values.
