Litle & Co. powers the payment processing engines for leading companies that sell directly to consumers through internet retail, direct response marketing (TV, radio and telephone), and online services. Litle & Co. is the leading, independent authority in card-not-present (CNP) commerce, transaction processing and merchant services.

The Litle PHP SDK is a PHP implementation of the Litle & Co.. XML API. This SDK was created to make it as easy as possible to connect process your payments with Litle. This SDK utilizes the HTTPS protocol to securely connect to Litle. Using the SDK requires coordination with the Litle team in order to be provided with credentials for accessing our systems.

Our PHP supports all of the functionality present in Litle XML v8. Please see the online copy of our [XSD for Litle XML] (https://github.com/LitleCo/litle-xml) to get more details on what is supported by the Litle payments engine.

This SDK is implemented to support the PHP programming language and was created by Litle & Co. It is intended use is for online transactions processing utilizing your account on the Litle payments engine.

See LICENSE file for details on using this software.

3. Configure the SDK:

cd litle/sdk php Setup.php

4. Run the attached sample:

<?php
require_once _DIR_.'/vendor/autoload.php';
#sale
$sale_info = array(
             'orderId' => '1',
             'amount'  => '10010',
             'orderSource' => 'ecommerce',
             'billToAddress' => array(
             'name' => 'John Smith' ,
             'addressLine1' => ' 1 Main St.',
             'city' => 'Burlington' ,
             'state' => 'MA' ,
             'zip' => '0183-3747',
             'country' => 'US'),
             'card' => array(
             'number' => '5112010000000003',
             'expDate' => '0112',
             'cardValidationNum' => '349',
             'type' => 'MC' )
            );
$initilaize = new litle\sdk\LitleOnlineRequest();
$saleResponse =$initilaize->saleRequest($sale_info);
#display results
echo ("Response: " . (litle\sdk\XmlParser::getNode($saleResponse,'response')) . "<br>");
echo ("Message: " . litle\sdk\XmlParser::getNode($saleResponse,'message') . "<br>");
echo ("Litle Transaction ID: " . litle\sdk\XmlParser::getNode($saleResponse,'litleTxnId'));

php your_sample_name

If you're not, you have to add a require for each and every class that's going to be used.

1. Configure the SDK

cd into litle/sdk php Setup.php

2. Add the litle folder and require the path for your file

3. run your file

php your_file

1. Install the LitleOnline PHP SDK from git.

git clone git://github.com/LitleCo/litle-sdk-for-php.git

php ~/composer.phar install

2. Once the SDK is downloaded run our setup program to generate a configuration file.

cd litle-sdk-for-php/lib

php Setup.php

Running the above commands will create a configuration file in the lib directory.

3. Create a symlink to the SDK

ln -s /path/to/sdk /var/www/html/nameOfLink

4.) Create a php file similar to:

<?php
require_once realpath(dirname(__FILE__)) . '/../lib/LitleOnline.php';  
    // Visa $10.00 sale
    $hash_in = array(
	      'amount'=>'106',
	      'orderId' => '123213',
	      'orderSource'=>'ecommerce',
	      'card'=>array(
	      'type'=>'VI',
	      'number' =>'4100000000000001',
	     'expDate' =>'1000')
	      );
//Perform the transaction on the Litle Platform
$initialize = new LitleOnlineRequest();
$saleResponse = $initialize->saleRequest($hash_in);

// Display Result 
echo ("Message: " . XMLParser::getNode($saleResponse,'message') . "<br>");
echo ("Litle Transaction ID: " . XMLParser::getNode($saleResponse,'litleTxnId'));

As of 8.13.1, you may also use a tree-oriented style to get the response values:

<?php
require_once realpath(dirname(__FILE__)) . '/../lib/LitleOnline.php';  
    // Visa $10.00 sale
    $hash_in = array(
	      'amount'=>'106',
	      'orderId' => '123213',
	      'orderSource'=>'ecommerce',
	      'card'=>array(
	      'type'=>'VI',
	      'number' =>'4100000000000001',
	     'expDate' =>'1000')
	      );
//Perform the transaction on the Litle Platform
$initialize = new LitleOnlineRequest($treeResponse=true);
$saleResponse = $initialize->saleRequest($hash_in);

// Display Result 
echo ("Message: " . $saleResponse->saleResponse->message . "<br>");
echo ("Litle Transaction ID: " . $saleResponse->saleResponse->litleTxnId);

NOTE: you may have to change the path to match that of your filesystems.

If you get an error like:

PHP Fatal error:  require_once(): Failed opening required '/home/gdake/git/litle-sdk-for-php/../lib/LitleONline.php' (include_path='.:/usr/share/pear:/usr/share/php') in /home/gdake/git/litle-sdk-for-php/foo.php on line 2

You need to change the second line of your script to load the real location of LitleOnline.php

If you get an error like:

PHP Fatal error:  require(): Failed opening required '/home/gdake/litle-sdk-for-php/lib/../vendor/autoload.php' (include_path='.:/usr/share/php:/usr/share/pear') in /home/gdake/litle-sdk-for-php/lib/LitleOnline.php on line 42

You probably had a problem with composer. You can safely remove line 42 if you are not using batch processing, or you can edit it to point at our dependencies that you've downloaded in another way.

5. Next run this file using php on the command line or inside a browser. You should see the following result provided you have connectivity to the Litle certification environment. You will see an HTTP error if you don't have access to the Litle URL

   Message: Valid Format Litle Transaction ID:
