Array
(
    [title] => CBS Blocks Time
    [link] => Array
        (
            [0] => http://techcrunch.com/2013/08/02/cbs-blocks-time-warner-cable-subscribers-from-watching-full-episodes-on-cbs-com/

    [dc_creator] => Ryan Lawler
    [dc_language] => en
    [dc_format] => text/html
)

这是我的方法

    $result = array();
foreach($item as $val){
    foreach($item['footnote'] as $val1){
        $result['link'] = $val1;
    }
}
pr($result);

Answer 1

$array['link'] = array_merge(array($array['link']), $array['footnote']);
unset($array['footnote']);
print_r($array);

Answer 2

应该这么简单：

$array['footnote'][] = $array['link'];
$array['link'] = $array['footnote'];
unset($array['footnote']);

Answer 3

foreach($array as $key=>$value) {
  if ($key == 'link') {
    $array[$key] = $array['footnote'];
    $array[$key][] = $value;  
    unset($array['footnote']);
    continue;
  }
}
