你能在mailjet中设置数组吗？

$myArray = array("Item 1", "Item 2", "Item 3");

$mailjet = new \Mailjet\Client('YOUR_API_KEY', 'YOUR_API_SECRET_KEY', true, ['version' => 'v3.1']);
$data = [
    'Messages' => [
        [
            'From' => [
                'Email' => "sender@example.com",
                'Name' => "Sender Name"
            ],
            'To' => [
                [
                    'Email' => "recipient@example.com",
                    'Name' => "Recipient Name"
                ]
            ],
            'Subject' => "Mailjet Test Email",
            'TextPart' => "Hello, this is a test email",
            'HTMLPart' => "<h3>Hi, this is a test email</h3>",
            'Variables' => [
                'myArray' => $myArray
            ]
        ]
    ]
];
$response = $mailjet->post(\Mailjet\Resources::$Email, ['body' => $data]);

<p>My Array: {{var:myArray}}</p>
