laravel return two meged response

I have a function in my laravel projrct that uses another function to send otp sms, but when I run the second function, and after return the response ,laravel return a merged response: first one is response of the second function and another one is my custom response,
my code is here:

$otp=rand(12345,99999);
            
             VerificationCode::create([
                'mobile'=>$mobile,
                'otp'=>$otp,
                'expire_at'=>Carbon::now()->addMinutes(10)

            ]);
            $this->sendSms($otp,$mobile);
            return response([
        'result'=>'verificationCode has sent',
        'message'=>'ok',
        'status'=>'200'
    ]);

and second function is:

public function sendSms($otp,$mobile){    
$post_data = http_build_query($data);
        $handle = curl_init('https://example.com/api/SendSMS/BaseServiceNumber');
        curl_setopt($handle, CURLOPT_HTTPHEADER, array(
            'content-type' => 'application/x-www-form-urlencoded'
        ));
        // curl_setopt($handle, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($handle, CURLOPT_SSL_VERIFYHOST, false);
        curl_setopt($handle, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($handle, CURLOPT_POST, true);
        curl_setopt($handle, CURLOPT_POSTFIELDS, $post_data);
        curl_setopt($handle, CURLOPT_RETURNTRANSFER, false);
       $response= curl_exec($handle);
        curl_close($handle);
        return $response;
}

the returned response is:

{"Value":"5589489218988866748","RetStatus":1,"StrRetStatus":"Ok"}{"result":null,"message":"ok","status":"200"}

why this part ({"Value":"558948925522554445","RetStatus":1,"StrRetStatus":"Ok"}) is added to the initial of the response?

    The issue is caused by the curl_setopt($handle, CURLOPT_RETURNTRANSFER, false); line in the sendSms function. When you set CURLOPT_RETURNTRANSFER to false, the curl_exec function directly outputs the response instead of returning it as a string. This causes the response from the SMS API to be sent directly to the output, and then your custom response is appended to it.

    To fix this issue, change the CURLOPT_RETURNTRANSFER option to true:

    curl_setopt($handle, CURLOPT_RETURNTRANSFER, true);

    This will make curl_exec return the response as a string, which you can then store in the $response variable. Since you’re not using the $response variable in your main function, you can remove the return $response; line from the sendSms function.

    $post_data = http_build_query($data);
$handle = curl_init('https://example.com/api/SendSMS/BaseServiceNumber');
curl_setopt($handle, CURLOPT_HTTPHEADER, array(
    'content-type' => 'application/x-www-form-urlencoded'
));
curl_setopt($handle, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($handle, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($handle, CURLOPT_POST, true);
curl_setopt($handle, CURLOPT_POSTFIELDS, $post_data);
curl_setopt($handle, CURLOPT_RETURNTRANSFER, true); // Change this line
$response = curl_exec($handle);
curl_close($handle);
// Remove the return statement

    Now, when you call the sendSms function, it won’t output the SMS API response directly, and you should only see your custom response in the output.

    Here’s a common pattern for sending an OTP SMS and returning a response in a Laravel controller:

    use IlluminateHttpRequest;
    use TwilioRestClient; // Assuming you’re using Twilio for sending SMS

    class MyController extends Controller
    {
    public function sendOtp(Request $request)
    {
    // Logic to generate and send OTP via SMS
    $otp = generateOTP();
    $phoneNumber = $request->input(‘phone_number’);

        // Use Twilio or another service to send the OTP via SMS
    $twilio = new Client(config('services.twilio.sid'), config('services.twilio.token'));
    $twilio->messages->create(
        $phoneNumber,
        [
            'from' => config('services.twilio.from'),
            'body' => "Your OTP code is: $otp",
        ]
    );

    // Return a response indicating success
    return response()->json(['message' => 'OTP sent successfully'], 200);
}

    }

    We generate an OTP and send it via SMS using the Twilio API.

    We return a single response using response()->json(…) to indicate that the OTP was sent successfully. This is a standard way to return responses in Laravel.

    Ensure that you don’t have any other code in your controller method that returns a response, as that might lead to merged responses. Review your code and make sure that only one response is being returned at the end of the method.
