使用php更新mysql json数组

$servername = "数据库服务器地址";
$username = "数据库用户名";
$password = "数据库密码";
$dbname = "数据库名";

// 使用mysqli扩展连接数据库
$conn = new mysqli($servername, $username, $password, $dbname);

// 使用PDO扩展连接数据库
$conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);

$sql = "UPDATE 表名 SET data = JSON_SET(data, '$.key', 'value') WHERE 条件";

if ($conn->query($sql) === TRUE) {
    echo "更新成功";
} else {
    echo "更新失败: " . $conn->error;
}

$conn->close();

$servername = "数据库服务器地址";
$username = "数据库用户名";
$password = "数据库密码";
$dbname = "数据库名";

// 使用mysqli扩展连接数据库
$conn = new mysqli($servername, $username, $password, $dbname);

// 使用PDO扩展连接数据库
$conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);

// 更新语句
$sql = "UPDATE 表名 SET data = JSON_SET(data, '$.key', 'value') WHERE 条件";

if ($conn->query($sql) === TRUE) {
    echo "更新成功";
} else {
    echo "更新失败: " . $conn->error;
