Introduction to Web Services<\/h2>\n
\nWeb Services is a system which enables and supports interoperability. It enables applications written in different languages, located in different places, running on different operating systems, to talk to each other, exchange information and perform different operations. The building blocks of Web Services are a
\nset of XML based standards namely SOAP (Simple Object Access Protocol), WSDL
\n(Web Services Description Language) and UDDI (Universal Description, Discovery,
\nand Integration).\n <\/div>\n

\nThe above diagram is the simplest diagram which can help you visualize web
\nservices, and shows how two remote applications can interact with each
\nother using web services. The protocol used for this remote interaction is SOAP.\n <\/div>\n

Simple Object Access Protocol (SOAP)<\/h2>\n
\nSOAP is a lightweight protocol for the exchange of information in a distributed environment. It is an XML-based protocol. The most important aspect of SOAP is its simplicity and extensibility. A SOAP message contains data in the form of XML. SOAP consists of three parts:<\/p>\n
    \n
  1. It is a framework for describing what is in a message and how to process the message\n<\/li>\n
  2. It is a set of Encoding rules\n<\/li>\n
  3. It is a convention for representing remote procedure calls (request and response)\n<\/li>\n<\/ol>\n<\/div>\n

    PHP and web Services<\/h2>\n
    \nPHP is a widely used general purpose scripting language. It is basically a procedural
    \nlanguage, but it has the capabilities of an object oriented language also. Its syntax
    \nis similar to Perl, C, Java, etc. It can be very easily embedded in the HTML which
    \nmakes web developement using PHP very easy. Some of the features of PHP which enhanced its capability for Web services development are discussed below.\n <\/div>\n
