У меня есть быстрый запрос о том, как преобразовать многомерный массив в одномерный массив
$teachers=array(array('post_id' => "John Doe",'video_id' => array('Government','English')), array('post_id' => "Steven Lee",'video_id' => array("Math","Science", "PE")),array('post_id' => "Jean Perot", 'video_id' => array("French", "Literature")));
попробуй это
function array_values_recursive($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 )
