How To Return The Date From A Web Service

In the previous few years, new Web companies have been popping up all around the Internet. From September 2007 to June 2009, we supported two variations of PHP aspect by aspect: PHP four and PHP 5. By default, a consumer’s PHP scripts ran in PHP 4, unless they opted to make use of PHP 5. To full the example, let’s create a consumer to eat the Web service we simply created.

As you possibly can see there is nothing magic in an internet service that extracs data from a database, plain PHP comes by default with all the instruments needed, more complicated libraries could also be included into your venture (only) to solve particular problems.

However, provided you keep the default permissions on your public_html directory, as originally set up by CIS, you should not have to explicitly change any file or listing premissions to ensure that PHP 5 to work. We will use PEAR, which is just isn’t a standalone package deal for Web providers but extra of a framework for constructing PHP purposes, and which includes a Web providers module.

These two declarations kind an integral half in the technology of the WSDL file for our Web service. You can query your PHP model by executing the command php -version from a shell immediate. Before we create a SOAP server we need to create a WSDL doc defining the web service. After declaring our foremost Web companies class named Sales, we outline an array field named $__dispatch_map and a corresponding constuctor class.

If we detect an specific request technique then the service method is invoked on the $server occasion defined previously, which returns a Web service outcome. In the above, we declare the method getPrice to be a Web service API by marking it with the tag @soap in its doc comment. A web service is outlined with a WSDL (Web Services Description Language) doc, and different systems interact with the net service utilizing SOAP messages, transferred utilizing HTTP with an XML serialization.
