Whether you are sharing knowledge between two inside programs or building an API so customers can access their knowledge, this sensible book gives every part it’s essential to construct net service APIs with PHP. It is necessary for the online server account (httpd) to have learn entry to the listing (as was the case for PHP 4 scripts, and for static HTML pages and style sheets, and many others), but httpd does not need any access to the PHP 5 script itself.
In case you do not have an active connection, you have to to obtain the SOAP package deal for PEAR as well as some prerequisite PEAR modules from as a way to set up the SOAP bundle, together with Mail_Mime, Net_URL, HTTP_Request, and Net_DIME. The cleaning soap:body factor specifies how the message elements appear contained in the SOAP Body factor.
Although not a prerequisite for the following article, studying it provides you with a firmer grasp on the whole Web providers image, since you will be able to make use of the PHP Web service described right here to communicate with another service written in Java, and vice versa, allowing you to experiment firsthand with Web companies interoperability.
WSDL is an XML document in the namespace for describing an online service as a set of endpoints operating on messages. Soap:Envelope is obligatory, but the next factor, soap:Header, is non-compulsory and normally contains information relevant to authentication and session handling. The SOAP extension and the XML-RPC extension are usually not enabled by default in a PHP installation. Yii depends on doc remark and class reflection to determine which strategies might be remotely invoked and what are their parameters and return worth. The Web service now we have designed in PHP lets you use this similar mechanism of appending the ?wsdl to the request with a view to receive the WSDL. The SOAP library provides various features for making a SOAP server and a SOAP client. The Web service shopper first imports the SOAP/ library used in coding PEAR’s Web providers clients.
This would possibly appear like simply an abnormal XML file, but what makes it a SOAP message is the foundation aspect Envelope with the namespace cleaning soap as -envelope. The example client is written in PHP, but it may very well be in different languages, similar to Java, C#, Flex, and so forth. The following service is kind of similar to the one described in my earlier Java Web services article.
