Question

我有一个非常基本的列表查询，我想在一个数组中显示所有列表

$sql = "SELECT * FROM vendor";
$result = mysqli_query($conn, $sql);
if (mysqli_num_rows($result) > 0) 
    {
        while($row = mysqli_fetch_assoc($result)) 
            {
                echo"<pre>";
                    print_r($row);
                echo "</pre>";
            }
    }

我的结果为

Array
(
    [id] => 1
    [email] => 
    [password] => 
    [status] => 
)

Array
(
    [id] => 2
    [email] => 
    [password] => 
    [status] => 
)

Array
(
    [id] => 3
    [email] => 
    [password] => 
    [status] => 
)

但是我希望得到的结果看起来像这样。

Array
(
   [0] => Array
    (
        [id] => 1
        [email] => 
        [password] => 
        [status] => 
    )
   [1] => Array
    (
        [id] => 1
        [email] => 
        [password] => 
        [status] => 
    )
)

任何人都可以告诉我如何获得这个结果

Answer 1

您只需将行插入父数组，以获得所需的输出。通过在开始循环结果之前声明一个空数组，然后将每一行推入该父数组来执行此操作。见下文。

$sql = "SELECT * FROM vendor";
$result = mysqli_query($conn, $sql);
$res = array(); // parent array here
if (mysqli_num_rows($result) > 0) 
    {
        while($row = mysqli_fetch_assoc($result)) 
            {
                $array[] = $row; // push row into parent array
            }
    }
echo "<pre>"; 
print_r($res);
echo "</pre>";

Answer 2

首先，您需要将所有行存储到attaylist中，然后打印

$sql = "SELECT * FROM vendor";
$result = mysqli_query($conn, $sql);
$resulyArray = array();
if (mysqli_num_rows($result) > 0) 
    {
        while($row = mysqli_fetch_assoc($result)) 
            {
    array_push($resulyArray , $row);


            }
    } 


echo"<pre>";
  print_r($resulyArray);
echo "</pre>";

从不同的值创建单个数组
