示例。我有：
Array (
[0] => Array (
[comments_id] => 1
[comments_text] => blabla1
)
[1] => Array (
[comments_id] => 2
[comments_text] => blabla2
)
)
我想要：
Array (
[comments_id] => Array (
[0] => 1
[1] => 2
)
[comments_text] => Array (
[0] => blabla1
[1] => blabla2
)
在简化中要替换$array[x][y]至$array[y][x]我用php编写。
你可以像这样做
// the final array which will hold your result array
// considering $results contains your previous array
$final_array = array();
foreach($results as $result) {
$final_array['comments_id'][] = $result['comments_id'];
$final_array['comments_text'][] = $result['comments_text'];
}
