如果没有我所做的 foreach，我如何批量发送给所有客户。我只想通过 1 条消息发送给所有人。

public function sendToMany(Request $request){

    $number = getenv('TWILIO_NUMBER'); //Twilio's number

    $sid    = getenv('TWILIO_ACCOUNT_SID');//////////////////////
    $token  = getenv('TWILIO_AUTH_TOKEN'); // API credentials  //
    $twilio = new Client($sid, $token);    //////////////////////

    $otp = $request->message;//message from the form

    $receiver = array("+xxxxxxxxxxxx", "+xxxxxxxxxxxx", "+xxxxxxxxxxxx");

    foreach ($receiver as $receiver_number){
        $message = $twilio->messages 
        ->create("whatsapp:".$receiver_number, // to 
                array( 
                    "from" => "whatsapp:".$number,    
                    "body" => $otp  //message to send
                ) 
                );
    }//end of for loop
}//end of method
