php curl函数封装

<?php
function curl_request($url, $method = 'GET', $data = null, $headers = []) {
    $ch = curl_init();

    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch => CURLOPT_RETURNTRANSFER, true);

    if ($method == 'POST') {
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    } elseif ($method == 'PUT') {
        curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT');
        curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
    } elseif ($method == 'DELETE') {
        curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'DELETE');
    }

    if (!empty($headers)) {
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    }

    $response = curl_exec($ch);
    $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);

    curl_close($ch);

    return ['response' => $response, 'httpCode' => $httpCode];
}

// 示例调用
$url = 'https://api.example.com/data';
$data = ['key' => 'value'];
$headers = ['Content-Type: application/json'];

$result = curl_request($url, 'POST', json_encode($data), $headers);
print_r($result);
