PHP is a server-side programming language that provides some great website design functionality with so many attributes and coloration with HTML. One of the best advantages of the Php is that is a precoded language, that is you n don’t need to rewrite the basic codes every time while creating the web page you just need to alter some codes to alter the design of the website this saves lots of time of the developers and programmers.

System requirements

 

Web server
Any web server and any operating system can be used. You can use Apache V2.X or IBM’s HTTP Server; for the best experience in the Php. You may download from Apache or IBM.

 

PHP
PHP V5.1 is an ideal version for PHP and it has got all the utilities with most defined PHP data objects required for creating a web page. Just make sure that to configure with the required support from the derby and the soap extension with all the integrated modules.

 

Database
You may create different types of database tables and queries using the PHP code. But before creating the database, it is a good idea to know exactly what you are creating and how you are creating. There are different types of databases that are compatible with the Php programming. My SQL and RDBMS are two of the most popular databases, mostly used by the programmers. Apart from that, you have got some other choices as well, depending on your needs and requirements for PHP Development.. The apache is best suited with Derby and IMB hence if you are going for a more complex programming job then better consider these databases.

Starting with SOAP

SOAP which is the abbreviation of the Simple Object Access Protocol that allows different programs to run on the disparate operating systems simultaneously clubbing with the XML, HTTP and SMTP.  The purpose of soap is to induce the extensibility, accessibility and interdependence of the operating systems through a dedicated message format that enhances the capability of the operating system.

 

Characteristics of SOAP

SOAP has numerous characteristics as it provides the Messaging Protocol layer for web services for the slack. It is an XML-based protocol consisting of three parts:

  • It is a rule for representing responses and procedure calls
  • It defines the type of the message structure and how it proceeds
  • It defines the set of encoding rules for application-defined data types

 

SOAP has three major characteristics:

  • Extensibility – This unique property of SOAP allows programmers to access the security and WS-routing and several other extensions in the single platform.
  • Neutrality – The best part of SOAP is that it can be operated and clubbed with the various HTTP protocols like  SMTP, TCP, UDP, or JMS
  • Independence – SOAP is the most efficient platform to enhance the compatibility of the system by allowing access and integration to various programs and programming models.

SOAP STRUCTURE

SOAP comes in the XML and has a pretty familiar structure. Let’s check the SOAP structure and its format.

Building a SOAP Server

The best way to create SOAP Server is through the NuSOAP.  Just go to the sourceforge.net/projects/nusoap, and download the package with web directory and now unzip the package and create a nusoap.php file.

Given the product category, the server should read the category from the request hence it is a preferable choice to create a product list Php file first like productlist.php.

Building a SOAP Client Server

Fist create a product list php file naming productlistclient.php

The constructor takes the location of the newly created SOAP server to connect. Before creating a new instance of nusoap_client, first create a client file again include nusoap.php with require_once. The getError() is the best way to check whether the client server files are created correctly and adhere to the coding rules.
