关于PHP数组的问题！

Question

Array ( 
 [0] => Array ( [addBillAmount] => Array ( [0] => addUser [1] => amountRemarks ) )
 [1] => Array ( [addBillPrice] => Array ( [0] => addUser [1] => priceRemarks ) ) 
)

Array ( 
  [addBillAmount] => Array ( [0] => addUser [1] => amountRemarks ) 
  [addBillPrice] => Array ( [0] => addUser [1] => priceRemarks )
)

PHP如何把第一种数组格式转换成第二种呢，我是初学。把代码写出来！

Answer 1

function array_key_up($array){
    $data=[];
    foreach ($array as $value){
        foreach ($value as $k=>$v){
            $data[$k] = $v;
        }
    }
    return $data;
}
$array=Array (
0 => Array ( 'addBillAmount' => Array ( 0=> 'addUser' ,1 => 'amountRemarks' )),
1 => Array ( 'addBillPrice' => Array ( 0 => 'addUser' ,1 => 'priceRemarks' ) )
);
print_r(array_key_up($array));
