我正在尝试从Textlocal实现下面的SMS API。我在其中收到了。我想向在此网站上下订单的客户发送自动订单确认短信。http://52.77.236.176/

    <?php
    // Textlocal account details
    $username = \'[email protected]\';
    $hash = \'Your API hash\';

    // Message details
    $numbers = array(918123456789, 918987654321);
    $sender = urlencode(\'TXTLCL\');
    $message = rawurlencode(\'This is your message\');

    $numbers = implode(\',\', $numbers);

    // Prepare data for POST request
    $data = array(\'username\' => $username, \'hash\' => $hash, \'numbers\' => $numbers, "sender" => $sender, "message" => $message);

    // Send the POST request with cURL
    $ch = curl_init(\'http://api.textlocal.in/send/\');
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    $response = curl_exec($ch);
    curl_close($ch);

    // Process your response here
    echo $response;
?>

现在，我对在wordpress中应该把代码放在哪里感到困惑。我是说在哪一页？
