我希望将$myArray的所有值都插入数据库

但是我也使用foreach循环将其存储到$variable中，我只是将值隐含在查询中。

INSERT INTO test(code,contents) VALUES $variable;

这是我在做什么。

$hotel_content = '';
foreach($myArray as $content)
{
  $hotel_content  .= "(".$content['code'].",".json_encode($content)."),";
}

$hotel = "INSERT INTO test(code,contents) VALUES ".rtrim($hotel_content,",").';';

if (!$conn) {
      die("Connection failed: " . mysqli_connect_error());
}

if (mysqli_query($conn, $hotel) ) 
{
    echo "You have successfully inserted the data.";
} 
else 
{
  echo "Error: " . $hotel . "<br>" . mysqli_error($conn);
}

mysqli_close($conn);

Answer 1

方法1： 您可以通过将其转换为sting来插入完整数组。因此，您可以在插入之前使用PHP serialize函数。

$serialized_data = serialize($myarray);

然后将用户$serialized_data插入您的插入查询中。 参考：https://www.php.net/manual/en/function.serialize.php

注意，您将在使用此数据时取消序列化。因此，从数据库中检索后，可以通过unserialize()函数对其进行反序列化。

另一种方式：您可以使用json_encode()函数来存储array。并且您还需要在何时/何地使用此数据使用json_decode()。

参考：https://www.php.net/manual/en/function.json-encode.php

Answer 2

将表列定义为longText  像这样

 $table->longText('column_name');

然后将数据另存为JSON STRING

$value = json_encode($myArray);
