Send SMS in Hindi Using API

Send Hindi SMS using API is not that easy as it look like. While working on a project i have to send Hindi SMS and when i write hindi in message and send it to the mobile. It shows me ?????????????? ???????? ????? like this. So i figured out if we use unicode to send the message than we can send the SMS in Hindi or other language. This tutorial is about to send SMS in Hindi.

In this tutorial we are using the Bulk SMS API form Simply IT Solutions Pvt Ltd. They are providing fast and perfect delivery.

So here is the magical function to change your message to the UNICODE message.

$str="98XXXXXXXX  100 रु का रीचार्ज किया गया है|"; // Our SMS
$msg=str_replace('%u', '',$smsClass->utf8_to_unicode($str));//it will convert the normal message to the unicode

Above line will change the message to the Unicode By using the below function.

public function utf8_to_unicode($str) {
$unicode = array();
$values = array();
$lookingFor = 1;
for ($i = 0; $i < strlen($str); $i++) {
    $thisValue = ord($str[$i]);
    if ($thisValue < 128) {
        $number = dechex($thisValue);
        $unicode[] = (strlen($number) == 1) ? '%u000' . $number : "%u00" . $number;
    } else {
        if (count($values) == 0)
            $lookingFor = ( $thisValue < 224 ) ? 2 : 3;
        $values[] = $thisValue;
        if (count($values) == $lookingFor) {
            $number = ( $lookingFor == 3 ) ?
                    ( ( $values[0] % 16 ) * 4096 ) + ( ( $values[1] % 64 ) * 64 ) + ( $values[2] % 64 ) :
                    ( ( $values[0] % 32 ) * 64 ) + ( $values[1] % 64
                    );
            $number = dechex($number);
            $unicode[] =
                    (strlen($number) == 3) ? "%u0" . $number : "%u" . $number;
            $values = array();
            $lookingFor = 1;
        } // if
    } // if
}
return implode("", $unicode);
}

After change the SMS to Unicode it will look like a list of many numbers. Now next part is to send the sms. As i told you earlier that we are using an API so we create a function and passing mobile no and message to that function.

public function shootUnicodeSMS($mobileno,$message){
$username="your username";
$password="your password";
$Senderid="your sender it";
$url ="http://tsms.simplyitsols.com/bulksms/bulksms?username=$username&password=$password&type=2&dlr=1&destination=$mobileno&source=$Senderid&message=$message";
$ch=curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$ab=curl_exec($ch);
curl_close($ch);
return $ab.",".$url;
}

It will send the SMS in Hindi. Hope you like it if you have any advice or comment than please write in the comment box.
