Hi! i'm currently have a problem using PHP in order to create a form that has the capability to send sms by using GSM modem, by the way, the modem that i'm using right now is Huawei E173 Broadband. I know there has been a lot of way to send sms using php but most of it is by using SMS Gateway, (eg like nowsms)

To the problem, I wanna know how do i make this form below to send sms, now i've know that my modem is on COM6, so how do i integrate this form below here with GSM modem to send sms by using php+


So now i really need help here to teach me and guide me so that i can make php uses gsm modem to send sms. Thank you so much!

 

 

Form:

 

<html>
<head>
<title>FORM TEST</title>
</head>

<body>
<form name="form1" action="" method="post">
Enter Mobile Number: <input type="text" name="text1"><br>
Enter SMS: <textarea cols="10" rows="10" name="text2"></textarea><br>
<input type="submit" name="submit1" value="Send SMS">
</form>

</body>
</html>

 

To make this form integrae with code below to send sms

 

example.php (my modem is using COM6)

<?php
include "php_serial.class.php";

// Let's start the class
$serial = new phpSerial;

// First we must specify the device. This works on both linux and windows (if
// your linux serial device is /dev/ttyS0 for COM1, etc)
$serial->deviceSet("COM6");

// Then we need to open it
$serial->deviceOpen();

// To write into
$serial->sendMessage("Hello !");

// Or to read from
$read = $serial->readPort();

// If you want to change the configuration, the device must be closed
$serial->deviceClose();

// We can change the baud rate
$serial->confBaudRate(2400);

// etc...
?>
