我認爲這會幫助你： http://stackoverflow.com/questions/2699086/sort-multi維數組的價值 –

我並不真正瞭解更低價銷售的含義，而是來自數據庫的這一結果？如果是的話，那麼你可以通過sql來進行排序。 – bugscoder

您需要使用usort函數http://php.net/manual/en/function.uksort.php。其餘的就是我的，你想達到什麼樣的解釋 - 在產品的line_total總和排序交易

$array = []; //your array 

function sumLinesTotal($product_list) { 
    return array_sum(array_map($product_list, function($product){ 
     return $product['line_total']; 
    }); 
} 

usort($array['Transactions'], function ($a, $b) { 
    return sumLinesTotal($a) < sumLinesTotal($b); 
});
