多次元配列を一次元配列に変換する方法について簡単な質問があります

$teachers=array(array('post_id' => "John Doe",'video_id' => array('Government','English')), array('post_id' => "Steven Lee",'video_id' => array("Math","Science", "PE")),array('post_id' => "Jean Perot", 'video_id' => array("French", "Literature")));

これを試して

function array_values_recursive($ary)  {
    $lst = array();
    foreach( array_keys($ary) as $k ) {
        $v = $ary[$k];
        if (is_scalar($v)) {
            $lst[] = $v;
        } elseif (is_array($v)) {
            $lst = array_merge($lst,array_values_recursive($v));
        }
    }
    return array_values(array_unique($lst)); // used array_value function for rekey
}

$teachers=array(
    array('post_id' => "John Doe",'video_id' => array('Government','English')), 
    array('post_id' => "Steven Lee",'video_id' => array("Math","Science", "PE")),
    array('post_id' => "Jean Perot", 'video_id' => array("French", "Literature")));

$flat = array_values_recursive($teachers);
print_r($flat); // OUTPUT : Array ( [0] => John Doe [1] => Government [2] => English [3] => Steven Lee [4] => Math [5] => Science [6] => PE [7] => Jean Perot [8] => French [9] => Literature )
