PHP JSON编码转换为cUrl的带方括号的多维数组

<?php

// 1. 创建多维数组
$data = [
    "user" => [
        "name" => "John Doe",
        "email" => "john.doe@example.com",
        "roles" => ["admin", "editor"]
    ],
    "settings" => [
        "notifications" => true,
        "theme" => "dark"
    ]
];

// 2. 将数组转换为 JSON
$jsonData = json_encode($data);

if ($jsonData === false) {
    // 处理 JSON 编码错误
    echo "JSON 编码错误: " . json_last_error_msg();
    exit;
}

// 3. 使用 cURL 发送 JSON 数据
$ch = curl_init('https://api.example.com/endpoint');

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, [
    'Content-Type: application/json',
    'Content-Length: ' . strlen($jsonData)
]);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonData);

$response = curl_exec($ch);

if ($response === false) {
    // 处理 cURL 错误
    echo "cURL 错误: " . curl_error($ch);
    curl_close($ch);
    exit;
}

curl_close($ch);

// 处理 API 响应
echo "API 响应: " . $response;

?>
