PHP - 將參數從數組傳遞到SQL查詢

Question

我有一個SQL查詢，我想根據不同的場景傳遞不同的參數。我不知道如何做到這一點。這是查詢：

$data = Engagement::leftJoin('user_engagement', 'engagements.id', '=', 'user_engagement.engagement_id') 
      ->select('engagement_id', 'engagements.question', 'engagements.id') 
      ->selectRaw('count(*) as count') 
      ->whereBetween('user_engagement.created_at', [$from.' 00:00:00', $to.' 00:00:00']) 
      ->groupBy('user_engagement.engagement_id') 
      ->orderBy('count', 'DESC') 
      ->take(5) 
      ->get()->toArray(); 

所以，我想這樣做什麼，會是這個樣子：

  $model = new Engagement; 
      $leftJoin = ['user_engagement', 'engagements.id', '=', 'user_engagement.engagement_id']; 
      $select = ['engagement_id', 'engagements.question', 'engagements.id']; 
      $whereBetween = 'user_engagement.created_at'; 
      $groupBy = 'user_engagement.engagement_id'; 

      $data = $model->leftJoin($leftJoin) 
      ->select($select) 
      ->selectRaw('count(*) as count') 
      ->whereBetween($whereBetween, [$from.' 00:00:00', $to.' 00:00:00']) 
      ->groupBy($groupBy) 
      ->orderBy('count', 'DESC') 
      ->take(5) 
      ->get()->toArray();

好像都leftJoin和select方法花費，而不是一個陣列的幾個參數的參數。此修復程序應該工作，但它不是推薦：

$leftJoin = [ 
    'user_engagement', 
    'engagements.id', 
    '=', 
    'user_engagement.engagement_id' 
]; 
$select = [ 
'engagement_id', 
'engagements.question', 
'engagements.id' 
]; 

… 

data = $model->leftJoin($leftJoin[0], $leftJoin[1], $leftJoin[2], $leftJoin[3]) 
->select($select[0], $select[1], $select[2]) 
… 

我勸你分裂成數組變量單獨或創建用於此目的的對象。

你也可以去使用ReflectionMethod::invokeArgs

我猜的更先進的方式是，它看起來像這樣：

$model = new Engagement; 
$leftJoin = ['user_engagement', 'engagements.id', '=', 'user_engagement.engagement_id']; 
$select = ['engagement_id', 'engagements.question', 'engagements.id']; 
$whereBetween = 'user_engagement.created_at'; 
$groupBy = 'user_engagement.engagement_id'; 

$reflectLeftJoin = new ReflectionMethod('Engagement', 'leftJoin'); 
$reflectSelect = new ReflectionMethod('Engagement', 'select'); 

$reflectSelect->invokeArgs($model, $reflectLeftJoin->invokeArgs($model, $leftJoin)) 
    ->selectRaw('count(*) as count') 
    ->whereBetween($whereBetween, [$from.' 00:00:00', $to.' 00:00:00']) 
    ->groupBy($groupBy) 
    ->orderBy('count', 'DESC') 
    ->take(5) 
    ->get()->toArray(); 

它未測試。
