将数组和post转换为sql数据库

Question

这是我的数组：

Array ( [0] => Natural Chlid 1 [1] => Natural Chlid 2 [2] => Natural Chlid 3 )

我如何做以下事项：

a）转换数据，以便可以通过php查询调用并插入db

b）将数据仅添加到数据库的一个FIELD（在这种情况下是一个名为'children'的字段）

Answer 1

您可能需要serialize()和unserialize()：

$data = array(
    0 => 'Natural Chlid 1',
    1 => 'Natural Chlid 2',
    2 => 'Natural Chlid 3'
);

// To save

$link = mysqli_connect('hostname', 'user', 'password', 'dbname');

if (mysqli_connect_errno()) {
    printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
}

$serialized = mysqli_real_escape_string($link, serialize($data));

$result = mysqli_query($link, "INSERT INTO table ('id', 'children') VALUES (123, '$serialized')");

if (!$result) {
    printf("Error message: %s\n", mysqli_error());
}

// To retrieve

$result = mysqli_query("SELECT * FROM table WHERE id=123");
$row = mysqli_fetch_assoc(result);

$data = unserialize($row['children']);
