How to access mysql result set data with a foreach loop（13个答案）
2天前关闭。
我正在从数据库中获取数据，结果如下：

Array
(
    [0] => Array
        (
            [username] => example@gmail.com
            [processedDate] => 2022-11-09 10:22:00
            [processed] => 1
        )

    [1] => Array
        (
            [username] => example@gmail.com
            [processedDate] => 0000-00-00 00:00:00
            [processed] => 0
        )

    [2] => Array
        (
            [username] => example@gmail.com
            [processedDate] => 2022-10-26 11:07:00
            [processed] => 1
        )

    [3] => Array
        (
            [username] => example@gmail.com
            [processedDate] => 2022-11-14 17:21:00
            [processed] => 1
        )

    [4] => Array
        (
            [username] => example@gmail.com
            [processedDate] => 2022-09-19 10:50:00
            [processed] => 1
        )
)

很酷，但是我需要访问，例如，username属性，这与我处理对象（$myArray->username）时的情况类似。
我试过了，但它不起作用，因为它不是一个对象，它是一个数组.

foreach($arr as $var) {
    foreach($var as $el) {
        echo $el->username;
    }
}

我也试过用这个：

foreach($arr as $var) {
    echo $var['username'];
}

我的目标是访问username、processedDate和processes属性，以便使用它们并评估条件。
我想得到的是：

Array
(
    [0] => Array
        (
            [username] => example@gmail.com
        )

    [1] => Array
        (
            [username] => example@gmail.com
        )

    [2] => Array
        (
            [username] => example@gmail.com
        )

    [3] => Array
        (
            [username] => example@gmail.com
        )

    [4] => Array
        (
            [username] => example@gmail.com
        )
)

这是我的完整代码：

$sql = "SELECT username, processedDate, processed FROM users_test";
$stmt = $conn->prepare($sql);
$stmt->execute();
$result = $stmt->get_result();

while ($row = $result->fetch_assoc()){
     $arr[] = $row;
}

echo "<pre>";
print_r($arr); // The result of this is the first code I posted here.
