As a server-side programming language, PHP isn't the right way to deal with a device like a modem. You can certainly do it by sending to a third party service or to the phone company server as an email (if they provide that service where you are). If you search this site you will find some previous posts about doing this directly through a modem but you will probably see that it is being done using C or Java.

Dear all, I got problem with looping i wanna get interest rate in each loop while date = date + 1month and round up-round down with all amount:

here is my code:

    $spit = array(",", "'");
    $loan = str_replace($spit,"",$loan_size);
        //echo"<script>alert('$loan');

    $date = date('Y-m-d');
    $naturity_date=date("Y-m-d",strtotime("+$term months"));    
    $repayment_date=date("$date",strtotime("+1 months"));   
    $days=abs(strtotime($repayment_date)-strtotime($date));

    $remain_days=floor($days/60/60/24);

        $ba=$loan;  
        $pr=round(doubleval($loan/$term),2);
        $i=floatval($rate/100);

    echo "<script>alert('$ba,$pr,$i,$remain_days,$cur');</script>";


    for($a=1;$a<=$term;$a++){
            $repay_date=date("D,d/M/Y",strtotime($next_month));

            $ba=round(($ba-$pr),2);
            $i=round((($ba*30*$i)/30),2);
            $pa=round(($pr+$i),2);  

    /*  echo"<script>alert('$i');</script>"; */
    /////////////////////////
        echo"<tr align='center'>
                <td class='tdborder'>
                    $a
                </td>
            ";

            echo"<td class='tdborder'>$repay_date</td>";
            echo"<td class='tdborder'>$cur $pr</td>";
            echo"<td class='tdborder'>$cur $i</td>";
            echo"<td class='tdborder'>$cur $pa</td>";
            echo"<td class='tdborder'>$cur $ba</td>";

        echo"</tr>";

        }

        ///////////

            echo"<tr align='center'>
                <td class='tdborder'>
