需要幫助來分組php陣列，使其更好

Question

首先，我的分組工作，但我覺得它很髒。需要有人讓它看起來更乾淨，更好。 我有以下的foreach

$data['new_array'] = array(); //I have to use $data['new_array'] because I need to pass it to template. 
foreach ($get_topics as $topic) { 
    //Is that possible to make these 4 lines shorter? 
    $data['new_array'][$topic['tid']]['tid'] = $topic['tid']; 
    $data['new_array'][$topic['tid']]['title'] = $topic['title']; 
    $data['new_array'][$topic['tid']]['yes'] = $topic['yes']; 
    $data['new_array'][$topic['tid']]['no'] = $topic['no']; 

    //The belows are subarray grouping, it actually works but I need better solutions 
    //$new_array[$topic['tid']]['vid'][$topic['vid']][] = $topic['vid']; 
    //$new_array[$topic['tid']]['vid'][$topic['vid']][] = $topic['yesno']; 
} 

Answer 1

我不會試圖把它縮短，但這裏是你在一個漂亮的版本代碼。

$data['new_array'] = array(); 

foreach ($get_topics as $topic) { 
    $data['new_array'][$topic['tid']] = array(
     'tid' => $topic['tid'], 
     'title' => $topic['title'], 
     'yes' => $topic['yes'], 
     'no' => $topic['no'] 
    ); 
} 

不確定$ topic ['tid']是什麼類型，但使用非連續數字作爲數組鍵時應該小心。
