Class diagram
The diagram below is a class diagram for the classes that makes up the PHP WS. 
The project consists of six classes. The ESWebIntegrationWSPHP class, which is the main class, contains the web methods we are going to call and it consumes the other five classes. The sample code in the project is an integration with the open source web shop osCommerce and the database engine is MySQL.
Lets take a look at the classes and ESWebIntegrationWS.php file and explain the use of the them. The LoginCredentials class handles the credentials for user authentication based on the credentials that is used in Consignor. Every web method has LoginCredentials as an input parameter. You can use the credentials UserName and Password to authenticate the user or just one of them. In the sample code UserName is used to assign the database prefix, so the user gets access only to his tables in the database. $prefix = $Credentials['UserName'];.
The AddressData class handles the data we want to present on the receiver of the shipment. This class is used both in order (GetOrderData) and customer (GetCustomerData) lookup. Lines that are marked with * are mandatory and this means you have to assign a value to this AddressData class member in the functions GetOrderData and GetCustomerData. Edit the sample code to fit your needs of fields from the AddressData class.

AddressesAndPackages class consists of two data members that presents an instance of AdressData and LineData as arrays. These two members are used to return an array of the data members in AdressData and LineData from the functions GetOrderData and GetCustomerData.
The ReturnData class is used to return data on a shipment from Consignor and back to your system, so you are able to update your database based on the return data. The UpdateData function uses the ReturnData class for this purpose. ColliNumbers and PackageTrackUrl is semicolon( ; ) separated. ShipmentTrackUrl provides carriers track and trace URL with shipment number and PackageTrackUrl provides track and trace URL with package numbers.
| Field | Description | Value |
| OrderNumber | Order number | 12345 |
| PackagesCount | Number of packages | 2 |
| ShipmentNumber | Track & Trace shipment number, used for tracking shipment on carrier. | 5878892250 |

ESWebIntegrationWS.php
The ESWebIntegrationWS.php file contains all the functions (web methods) that is consumed from Consignor and our WS. The function GetOrderData handles order requests. It connects to the database and fetches the order data from SQL query. The function takes two input parameters, OrderNumber as a string and Credentials as LoginCredentials.
As mentioned before, use credentials to authenticate the user in the way that suits your needs. Use the data members you want from the classes AddressData (remember to include the mandatory members) and LineData. Do not edit any of the classes and keep the namespace as it is in the code: $NAMESPACE = 'http://localhost/ESWebIntegrationWS';.
Deploying the Web Service
To deploy the WS, simply do as you usually would do with an ordinary site. Include the folder "lib" and the file ESWebIntegrationWS.php and dbCon if you are going to use this for your database connection. When your WS is up and running, you should see a site as shown in the picture when you point to your URL. 
Download PHP Project files
To get started, download the project files below. Note that the project files were created with PHP 5.6. It contains a ready made webservice with sample code. Change the code and SQL queries to fit your system and the data you wish to provide with the web service.
