做與A組和（）的東西像MySQL查詢做，但在PHP多陣列

Question

這裏是我現在在做什麼東西，我從數據庫中像這樣的數組：

array (size=2) 
    0 => 
    array (size=13) 
     'wop_product_owner_id' => string '100007' (length=6) 
     'wop_product_id' => string '100002' (length=6) 
     'wop_product_price' => string '18.80' (length=5) 
     'wop_product_count' => string '2.00' (length=4) 
     'wop_product_unit' => string 'kg' (length=6) 
    1 => 
    array (size=13) 
     'wop_product_owner_id' => string '100007' (length=6) 
     'wop_product_id' => string '100001' (length=6) 
     'wop_product_price' => string '35.00' (length=5) 
     'wop_product_count' => string '4.00' (length=4) 
     'wop_product_unit' => string 'kg' (length=6) 

所有我需要做的是「* wop_product_price wop_product_count」合併的每個項目，總爲這個陣列，它具有相同的「wop_product_owner_id」在一個新的數組，新數組應該是這樣的：

array (size=1) 
    0 => 
     array (size=5) 
      'woner_id' => string '100007' (length=6) 
      'woner_name' => string 'Jack' (length=6) 
      'woner_photo' => string '' (length=5) 
      'woner_total' => float '177.6.00' 
      'woner_paid' => boolean 'false' 

基本上，就像你可以在Mysql中用sum（）和group進行查詢。 而且，我已經有辦法做到這一點，這裏是代碼：

$ tmps = array（）;

foreach ($products as $p) { 
     $owner_id = $p['wop_product_owner_id']; 

     if (empty($tmps)) { 
      $tmps[] = array(
       'woner_id' => $p['wop_product_owner_id'], 
       'woner_name' => $p['wop_product_owner_name'], 
       'woner_photo' => $p['wop_product_owner_photo'], 
       'woner_total' => (float) $p['wop_product_price'] * (float) $p['wop_product_count'], 
       'woner_paid' => (int) $p['wop_product_payment_id'] > 0 
      ); 
     } else { 
      foreach ($tmps as $key => $value) { 
       if (array_search($owner_id, $value) === FALSE) { 
        $tmps[] = array(
         'woner_id' => $p['wop_product_owner_id'], 
         'woner_name' => $p['wop_product_owner_name'], 
         'woner_photo' => $p['wop_product_owner_photo'], 
         'woner_total' => (float) $p['wop_product_price'] * (float) $p['wop_product_count'], 
         'woner_paid' => (int) $p['wop_product_payment_id'] > 0 
        ); 
       } else { 
        $tmps[$key]['woner_total'] = (float) $tmps[$key]['woner_total'] + (float) $p['wop_product_price'] * (float) $p['wop_product_count']; 
       } 
      } 
     } 
    } 

    return $tmps; 

但是，我實際上並不喜歡它，我以爲肯定會有比這更優美的方式！你怎麼看？有任何想法嗎？

Answer 1

您可以使用此

foreach ($products as $p) { 
    $owner_id = $p['wop_product_owner_id']; 

    if (empty($tmps[$owner_id])) { 
     $tmps[$owner_id] = array(
      'woner_id' => $p['wop_product_owner_id'], 
      'woner_name' => $p['wop_product_owner_name'], 
      'woner_photo' => $p['wop_product_owner_photo'], 
      'woner_total' => (float) $p['wop_product_price'] * (float) $p['wop_product_count'], 
      'woner_paid' => (int) $p['wop_product_payment_id'] > 0 
     ); 
    } else { 

       $tmps[$owner_id]['woner_total'] = (float) $tmps[$key]['woner_total'] + (float) $p['wop_product_price'] * (float) $p['wop_product_count']; 


    } 
} 

return $tmps; 

Answer 2

這裏是新的方式，從@budirec傳來：

$tmps = array(); 
    foreach ($products as $p) { 
     $owner_id = 'owner_' . $p['wop_product_owner_id']; 
     if (!isset($tmps[$owner_id])) { 
      $tmps[$owner_id] = array(
       'woner_id' => $p['wop_product_owner_id'], 
       'woner_name' => $p['wop_product_owner_name'], 
       'woner_photo' => $p['wop_product_owner_photo'], 
       'woner_total' => (float) $p['wop_product_price'] * (float) $p['wop_product_count'], 
       'woner_paid' => (int) $p['wop_product_payment_id'] > 0 
      ); 
     } else { 
      $tmps[$owner_id]['woner_total'] = (float) $tmps[$owner_id]['woner_total'] + (float) $p['wop_product_price'] * (float) $p['wop_product_count']; 
     } 
    } 

    return $tmps;
