Question

如何从以下mysql查询直接获得多维数组？

$query = SELECT * FROM table WHERE field1 = 1;

我尝试了以下内容：

$result = mysqli_query($connection, $query);

while ($row = mysqli_fetch_array($result)){
    $table[] = ($row['field1'].'~'.$row['field2'].'~'.$row['field3'].'~'.$row['field4']);
}

如果我们打印它，我们有以下结果：

array(
    [0] => 1 ~ ALFA  ~ beta   ~ 57
    [1] => 1 ~ BETA  ~ gamma  ~ 18
    [2] => 1 ~ GAMMA ~ delta  ~ 24
    ...
    [999] => 1 ~ ZETA ~ theta ~ 19
)

然后我必须将它爆炸以获得我希望的多维数组：

foreach ($table as $value) {
    $tableWithSubArrays[] = explode("~", $value);
}

然后我们得到了它：

Array(
    [0] => Array
        (
            [0] => 1
            [1] => ALFA
            [2] => beta
            [3] => 57
    )

    [1] => Array
        (
            [0] => 1
            [1] => BETA
            [2] => gamma
            [3] => 18
    )

    ...

    [999] => Array
        (
            [0] => 1
            [1] => ZETA
            [2] => theta
            [3] => 19
    )

有没有其他方法可以直接从查询到多维数组？

非常感谢提前！
