How to make separate config file for sms sending - api

Question

I have done a sms sending code in codeigniter. It is worked successfully. But actually i want to make a config file so that i will not write the username, password, senderid on each page.
Here is my code below. First i have done a library file for sms sending.
Sms.php
<?php
class SMS
{
function SendSMS($url)
{
if(function_exists('curl_init'))
{
$ch = curl_init();
$timeout = 60;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_HTTP_VERSION,CURL_HTTP_VERSION_1_0);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_TIMEOUT,$timeout);
$data = curl_exec($ch);
if($data === FALSE){
throw new Exception(curl_errno($ch));
}
curl_close($ch);
return $data;
}
else
{
return false;
}
}
}
?>
Again for sms sending i am writting code in each controller something like this.
$sms_username = "GAPSMS";
$sms_password = "GAPSMS";
$sms_senderid = "GAPSMS";
$sms_mobile = $mobile;
$sms_message = urlencode('Your One Time Password for transaction is: '.$otp);
$sms_api = "http://sendsms.sandeshwala.com/API/WebSMS/Http/v1.0a/index.php?username=$sms_username&password=$sms_password&sender=$sms_senderid&to=$sms_mobile&message=$sms_message&reqid=1&format={json|text}";
$this->sms->SendSMS($sms_api);
This much below code i want to write in a config file in such a way so that i can write this once and then can use in every controller to send sms.
$sms_username = "GAPSMS";
$sms_password = "GAPSMS";
$sms_senderid = "GAPSMS";

In CodeIgniter, libraries can have their own configuration file. Let's change your library a bit:
<?php
class Sms
{
private $_username = 'GAPSMS'; // default value
private $_password = 'GAPSMS'; // default value
private $_senderid = 'GAPSMS'; // default value
/**
* Class constructor so the config
* file is loaded.
*/
public function __construct($config = array())
{
if ( ! empty($config))
{
foreach ($config as $key => $val)
{
$this->{"_".$key} = $val;
}
}
}
function send($mobile, $message)
{
if(function_exists('curl_init'))
{
$url = 'http://sendsms.sandeshwala.com/API/WebSMS/Http/v1.0a/index.php?username='.$this->_username.'&password='.$this->_password.'&sender='.$this->_senderid.'&to='.$mobile.'&message='.$message.'&reqid=1&format={json|text}';
$ch = curl_init();
$timeout = 60;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_HTTP_VERSION,CURL_HTTP_VERSION_1_0);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_TIMEOUT,$timeout);
$data = curl_exec($ch);
if($data === FALSE){
throw new Exception(curl_errno($ch));
}
curl_close($ch);
return $data;
}
else
{
return false;
}
}
}
Then go create the config file application/config/sms.php inside which you put:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
$config['username'] = 'GAPSMS';
$config['password'] = 'GAPSMS';
$config['senderid'] = 'GAPSMS';
// End of file.
Now whenever the library is loaded, and config file is loaded as well as values are set, everything should work just fine. And the rest of the code would be:
// Load the library and simply pass mobile number and message.
$this->load->library('sms');
$data = $this->sms->send('0123456789', 'Hello, this is the message');
