从这个数组中获取歌曲

Question

我显然有问题.我一直在阅读Foreach循环手册,显然在一个循环中我需要来自阵列的所有歌曲,例如:

$music = array(
    'Creed' => array(
        'Human Clay' => array(
            array(
                'title' => 'Are You Ready'
            ),
            array(
                'title' => 'What If'
            ),
            array(
                'title' => 'Beautiful'
            ),
            array(
                'title' => 'Say I'
            ),
            array(
                'title' => 'Wrong Way'
            ),
            array(
                'title' => 'Faceless Man'
            ),
            array(
                'title' => 'Never Die'
            ),
            array(
                'title' => 'With Arms Wide pen'
            ),
            array(
                'title' => 'Higher'
            ),
            array(
                'title' => 'Was Away Those Years'
            ),
            array(
                'title' => 'Inside Us All'
            ),
            array(
                'title' => 'Track 12'
            ),
        ),
    ),
)

到目前为止我所拥有的是:

foreach($music['Creed']['Human Clay'] as $song){
   var_dump($song);
}

问题是,$ song是一个数组.我必须在一个循环中执行此操作.这可能吗？

Answer 1

是!

foreach($music['Creed']['Human Clay'] as $song){
   echo $song['title'];
}
