如何在php中发送多维数组post数据？

<?php
$data = array(
    'name' => 'John Doe',
    'age' => 30,
    'address' => array(
        'street' => '123 Main St',
        'city' => 'New York',
        'state' => 'NY'
    )
);

$postData = http_build_query($data);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://example.com/api');
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);
curl_close($ch);

echo $response;
?>
