The purpose of this article is to share with you what soap means in php. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Soap is based on XML and HTTP communication protocols. The way to use soap in php is to add php's soap module, that is, to add "soap.so" to php.ini.

What does php soap mean? What is wsdl and why use them?

SOAP is a language based on XML and HTTP communication protocols and supported by various platforms and languages of xml. Http is supported by all Internet browsers and servers.

WSDL refers to the Network Services description language (Web Services Description Language), which is a document written in XML. This kind of document can describe a Web service. It can specify the location of the service and the operations provided by the service.

I do php, you are java, and he does. Net. What if the three of us want to communicate and exchange data? We need a tool that can communicate with all of us. Soap,wsdl was created to enable applications running on different operating systems and using different technologies and programming languages to communicate with each other.

II. Examples

If php wants to use soap, the usual practice is to add the soap module of php, and add soap.so to php.ini. Here is a description that you can also implement soa without adding soap.so files.

/ / package nusoap.phprequire_once ('. / lib/nusoap.php'); / / create server $server=newsoap_server;// definition client call method $server- > register ('hello'); / / call method and parameter functionhello ($name) {return'Hello,'. $name;} $HTTP_RAW_POST_DATA= isset ($HTTP_RAW_POST_DATA)? $HTTP_RAW_POST_DATA:'';$server- > service ($HTTP_RAW_POST_DATA);? >

P's method

Nusoap is a functional document written by php, which can be used if it is included. Search for a lot of it on the Internet.

1. Do not use wsdl

A, server helloworld2.php

B. Client hello.php

/ / package nusoap.phprequire_once ('. / lib/nusoap.php'); / / create a new soap client and call wsdl//$client = newsoapclient ('http://localhost/test/hellowsdl2.php?wsdl', true) provided by the server; $client=newsoapclient (' http://localhost/test/helloworld2.php');// check to see if there is an error $err=$client- > getError (); if ($err) {/ / display error echo'Constructor error'.$err.'') } / / call the server method $result=$client- > call ('hello',array (' person'= > "this is a test"); echo'Result';print_r ($result); echo'';? >

2. Use wsld

A, server side

/ / package nusoap.phprequire_once ('. / lib/nusoap.php'); / / create a new soap service $server=newsoap_server (); / / initialize support for wsdl$server- > configureWSDL ('hellowsdl2','urn:hellowsdl2') / / define the data structure to receive data $server- > wsdl- > addComplexType ('Person','complexType','struct','all','',array (' firstname'= > array ('name'= >' firstname','type'= > 'xsd:string'), / / the following type defines the data type, this is string'age'= > array (' name'= > 'age','type'= >' xsd:int'), / / the subsequent type defines the data type This is int'gender'= > array ('name'= >' gender','type'= > 'xsd:string') / / the following type defines the type of data, this is string)) $server- > wsdl- > addComplexType ('SweepstakesGreeting','complexType','struct','all','',array (' greeting'= > array ('name'= >' greeting','type'= > 'xsd:string'),' winner'= > array ('name'= >' winner','type'= > 'xsd:string') / / the server-defined soap calling method $server- > register ('hello',// method name hello The method is in the following array ('person'= >' tns:Person'), / / the variable array ('return'= >' tns:SweepstakesGreeting') from the client, / / returns the parameter 'urn:hellowsdl2',// soap name', the method name of urn:hellowsdl2#hello',// soap, the way used by rpc',//, 'encoded',// encoding' test'// archive) / / define the function hellofunctionhello ($person) {$greeting='Hello,'. $person ['firstname']. It is nice to meet a'. $person ['age']. Year old'. $person ['gender'].'.; data to be returned by $winner='Scott';// returnarray ('greeting'= > $greeting,'winner'= > $winner);} / / call service $HTTP_RAW_POST_DATA= isset ($HTTP_RAW_POST_DATA)? $HTTP_RAW_POST_DATA:'';$server- > service ($HTTP_RAW_POST_DATA);? >

B, client

/ / package nusoap.phprequire_once ('. / lib/nusoap.php'); / / create a new soap client and call wsdl//$client = new soapclient ('http://localhost/test/hellowsdl2.php?wsdl', true) provided by the server; $client = new soapclient (' http://localhost/test/helloworld2.php');// check to see if there is an error $err = $client- > getError (); if ($err) {/ / display error echo 'Constructor error'. $err. ';} / parameters to be passed to the server $person = array (' firstname' = > 'Willi',' age' = > 22, 'gender' = >' male'); / / call server method $result = $client- > call ('hello', array (' person' = > $person)); / / error audit if ($client- > fault) {echo 'Fault';print_r ($result); echo';} else {$err = $client- > getError (); if ($err) {echo 'Error'. $err. '';} else {echo 'Result';print_r ($result); echo';}} / / displays the request information echo 'Request';echo'. Htmlspecialchars ($client- > request, ENT_QUOTES). ''; / / displays the returned message echo 'Response';echo'. Htmlspecialchars ($client- > response, ENT_QUOTES). ''; / / displays debug information echo 'Debug';echo'. Htmlspecialchars ($client- > debug_str, ENT_QUOTES). '';? >

The above two examples, both client-side and server-side, are written in php. You can try to write them in multiple languages to test them. Whether you use the php module or nusoap, the specific methods are not mentioned here, there are all in the manual.

There is no need to introduce SOAP here, here is just a simple implementation of an example of SOAP, not to mention, look at the code. Soap is divided into server and client, we want to make client to call server code. First, take a look at the short code of server:

This is the server side of the code: server.php

Then use the code on the client side to call the code on the server side: the code for client is also very simple:

This is the client side of the code client.php

Ok, it's over!
