Question

实际上，我正在获得阵列和子阵列。我想从子阵列中获取唯一值。我尝试了很多东西，但它对我不起作用。这是我的数组值

  Array

    [title] => Array
        (
            [0] => Cake Shops,Food,Inexpensive Restaurents,Moderate Restaurants (Rs.400 - Rs.800),Multicuisine Restaurants,Pure Veg Restaurants,Restaurants,Cake Shops,Food,Inexpensive Restaurents,Moderate Restaurants (Rs.400 - Rs.800),Multicuisine Restaurants,Pure Veg Restaurants,Restaurants,Cake Shops,Food,Inexpensive Restaurents,Moderate Restaurants (Rs.400 - Rs.800),Multicuisine Restaurants,Pure Veg Restaurants,Restaurants,Cake Shops,Food,Inexpensive Restaurents,Moderate Restaurants (Rs.400 - Rs.800),Multicuisine Restaurants,Pure Veg Restaurants,Restaurants,Cake Shops,Food,Inexpensive Restaurents,Moderate Restaurants (Rs.400 - Rs.800),Multicuisine Restaurants,Pure Veg Restaurants,Restaurants,Cake Shops,Food,Inexpensive Restaurents,Moderate Restaurants (Rs.400 - Rs.800),Multicuisine Restaurants,Pure Veg Restaurants,Restaurants,Cake Shops,Food,Inexpensive Restaurents,Moderate Restaurants (Rs.400 - Rs.800),Multicuisine Restaurants,Pure Veg Restaurants,Restaurants,Cake Shops,Food,Inexpensive Restaurents,Moderate Restaurants (Rs.,,

            [4] => ,,,Chocolate Manufacturers,,Chocolate Manufacturers,,Chocolate Manufacturers
            [5] => 
        )

)

我想要的只是从中获取唯一数据并删除空白值

我尝试过像

for($i=0;$i<count($listing);$i++){
        $tags['title'][$i] = $listing[$i]->cat_title;
        $tags['taa'] = array_unique($tags['title'][$i]);
    }
    echo '<pre>';
    print_r($tags);
    echo '</pre>';

在$listing我从db获取数据。

如何获得子阵列的唯一值？
