   // 客户端ssl证书
    curl_setopt($ch, CURLOPT_SSLCERT,  'ssl证书私钥指定文件');
    curl_setopt($ch, CURLOPT_SSLCERTPASSWD, '密码');
    curl_setopt($ch, CURLOPT_SSLCERTTYPE, 'PEM');

    // 私钥
    curl_setopt($ch, CURLOPT_SSLKEY,  'ssl证书私钥指定文件');
    curl_setopt($ch, CURLOPT_SSLKEYPASSWD, '密码');
    curl_setopt($ch, CURLOPT_SSLKEYTYPE, 'PEM');

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

// 指定客户端证书和密码
curl_setopt($ch, CURLOPT_SSLCERT, '/path/to/client_certificate.pem');
curl_setopt($ch, CURLOPT_SSLCERTPASSWD, 'certificate_password');

$response = curl_exec($ch);
if(curl_errno($ch)) {
    echo 'Curl error: ' . curl_error($ch);
}

curl_close($ch);

// 处理响应
echo $response;

CURLOPT_SSLCERT选项指定了客户端证书的路径，CURLOPT_SSLCERTPASSWD选项指定了客户端证书的密码。将这些选项设置为您的证书的实际路径和密码
