The following example PHP script, sendsms.php, can be used to send an SMS text message via NowSMS with PHP. This script can also be downloaded from http://www.nowsms.com/download/sendsms-php.txt.
<?php
function SendSMS ($host, $port, $username, $password, $phoneNoRecip, $msgText) {
/* Parameters:
$host - IP address or host name of the NowSMS server
$port - "Port number for the web interface" of the NowSMS Server
$username - "SMS Users" account on the NowSMS server
$password - Password defined for the "SMS Users" account on the NowSMS Server
$phoneNoRecip - One or more phone numbers (comma delimited) to receive the text message
$msgText - Text of the message
*/
$fp = fsockopen($host, $port, $errno, $errstr);
if (!$fp) {
echo "errno: $errno \n";
echo "errstr: $errstr\n";
return $result;
}
fwrite($fp, "GET /?Phone=" . rawurlencode($phoneNoRecip) . "&Text=" . rawurlencode($msgText) . " HTTP/1.0\n");
if ($username != "") {
$auth = $username . ":" . $password;
$auth = base64_encode($auth);
fwrite($fp, "Authorization: Basic " . $auth . "\n");
}
fwrite($fp, "\n");
$res = "";
while(!feof($fp)) {
$res .= fread($fp,1);
}
fclose($fp);
return $res;
}
/* This code provides an example of how you would call the SendSMS function from within
a PHP script to send a message. The response from the NowSMS server is echoed back from the script.
$x = SendSMS("127.0.0.1", 8800, "username", "password", "+44999999999", "Test Message");
echo $x;
*/
?>
The SendSMS function is the important part of the example. This is the function that needs to be included in your PHP script. You call this function, specifying the host name or IP address and port number of the NowSMS server, along with a username and password for an “SMS Users” account on the NowSMS server, plus the recipient phone number and text of the SMS message.
The SendSMS function uses these parameters to build a URL for connecting to the NowSMS server. This function could be easily modified to support sending other types of messages by modifying the URL that the function creates. For additional information on NowSMS URL parameters, see Submitting SMS Messages – URL Parameters.
As an additional example, here is how a web form might call a PHP script that uses sendsms.php to send an SMS message.
Below is a simple HTML web form that posts parameters to a PHP script named sendsmsscript.php:
<HTML>
<HEAD><TITLE>Send SMS</TITLE></HEAD>
<BODY>
<form method="post" action="sendsmsscript.php">
<table border="1">
<tr>
<td>Mobile Number:</td>
<td><input type="text" name="phone" size="40"></td>
</tr>
<tr>
<td valign="top">Text Message:</td>
<td><textarea name="text" cols="80" rows="10"></textarea>
</tr>
<tr>
<td colspan="2" align="center">
<input type="submit" value="Send">
</td>
</tr>
</table>
</form>
</BODY>
</HTML>
And here is an example sendsmsscript.php that processes the above form, validates the form parameters, and calls the SendSMS function from sendsms.php to submit the message:
if (isset($_REQUEST['phone'])) {
if (isset($_REQUEST['text'])) {
$x = SendSMS("127.0.0.1", 8800, "username", "password", $_REQUEST['phone'], $_REQUEST['text']);
echo $x;
}
else {
echo "ERROR : Message not sent -- Text parameter is missing!\r\n";
}
}
else {
echo "ERROR : Message not sent -- Phone parameter is missing!\r\n";
}
