面向对象的方式从表中选择记录并存储在多维数组中

Question

$select = SELECT * FROM `registration_form`;
$sql    = $conn -> query($select);

if ($sql->num_rows > 0) {
    $results = array();
    while ($rows = $sql -> fetch_assoc()) {
    $rows     = $rows['userName'];
    $password = $rows['password'];
    $name     = $rows['name'];
    $address  = $rows['address'];
    $country  = $rows['country'];
    $zipCode  = $rows['zipCode'];
    $email    = $rows['email'];
    $sex      = $rows['sex'];
    $language = $rows['language'];
    $about    = $rows['about'];
    }
} else {
    return false;
}

这是正常的PHP编码。但是我想知道如何改变面向对象的方式并以多维方式存储变量？我是PHP的初学者。

你有你的阵列：

$results = array();

你有你的循环：

while ($rows = $sql -> fetch_assoc()) {

只需将每一行添加到循环内的数组中：

$results = array();
while ($rows = $sql -> fetch_assoc()) {
    $results[] = $rows;
}
