Question

我有一个包含产品及其categoryID的数组，有些产品属于同一类别。数组的输出低于

array (size=5)
  'categoryID' => 
    array (size=3)
      0 => string '5' (length=1)
      1 => string '2' (length=1)
      2 => string '2' (length=1)
  'name' => 
    array (size=3)
      0 => string 'HP Player' (length=9)
      1 => string 'Android App' (length=11)
      2 => string 'TV' (length=2)
  'price' => 
    array (size=3)
      0 => string '600' (length=3)
      1 => string '111' (length=3)
      2 => string '1' (length=1)
  'qty' => 
    array (size=3)
      0 => string '22' (length=2)
      1 => string '22' (length=2)
      2 => string '222' (length=3)
  'exprice' => 
    array (size=3)
      0 => string '13200' (length=5)
      1 => string '2442' (length=4)
      2 => string '222' (length=3)

我想组合具有相同categoryID的产品，输出应如下所示：

array (size=2)
  => 0 array
  'categoryID' => 
    array 
      0 => string '5' (length=1)
   'name' => 
    array 
      0 => string 'HP Player' (length=9)
  'price' => 
    array 
      0 => string '600' (length=3)
  'qty' => 
    array 
      0 => string '22' (length=2)
  'exprice' => 
    array 
      0 => string '13200' (length=5)

   => 1 array
  'categoryID' => 
    array 
      0 => string '2' (length=1)
   'name' => 
    array 
     0 => string '2' (length=1)
     1 => string '2' (length=1)
  'price' => 
    array 
      0 => string '111' (length=3)
      1 => string '1' (length=1)
  'qty' => 
    array 
      0 => string '22' (length=2)
      1 => string '222' (length=3)
  'exprice' => 
    array 
      0 => string '2442' (length=4)
      1 => string '222' (length=3)

我怎么能这样做？感谢

$arr = array (
  'categoryID' => 
    array (
      0 => '5',
      1 => '2',
      2 => '2'
        ),
  'name' => 
    array (
      0 => 'HP Player',
      1 => 'Android App',
      2 => 'TV'
        ),
  'price' => 
    array (
      0 => '600',
      1 => '111',
      2 => '1'
        ),
  'qty' => 
    array (
      0 => '22',
      1 => '22',
      2 => '222'
        ),
  'exprice' => 
    array (
      0 => '13200',
      1 => '2442',
      2 => '222'
        )
    );

$cat_count = count(array_keys($arr['categoryID']));

$new_arr = array();
for($i=0;$i<$cat_count;$i++){
    for($j=0;$j<$i;$j++){
        if($arr['categoryID'][$i] == $arr['categoryID'][$j]){
            $arr_key = array_search($arr['categoryID'][$i], $arr['categoryID']);
            $cat_exists = 1;
        }
    }
        if($cat_exists){
            $new_arr[$arr_key]['name'][] = $arr['name'][$i];
            $new_arr[$arr_key]['price'][] = $arr['price'][$i];
            $new_arr[$arr_key]['qty'][] = $arr['qty'][$i];
            $new_arr[$arr_key]['exprice'][] = $arr['exprice'][$i];            
        }else{
            $new_arr[$i]['categoryID'][] = $arr['categoryID'][$i];
            $new_arr[$i]['name'][] = $arr['name'][$i];
            $new_arr[$i]['price'][] = $arr['price'][$i];
            $new_arr[$i]['qty'][] = $arr['qty'][$i];
            $new_arr[$i]['exprice'][] = $arr['exprice'][$i];            
        }
}

P.S :: $ arr 是输入数组＆amp; $ new_arr 是输出（结果）数组！

在阵列中组合相同类别的产品
