PHP Web Server Instance

With WebService, we can invoke programs that are deployed elsewhere without worrying about what platform the program was written in. Here we use PHP calls.

In the PHP4 era call WebService most of the nusoap used, to the PHP5 already have their own SOAP extension, we just need to open the extension in the PHP configuration file php.ini

Extension = Php_soap.dll

　　

Instance Program

Define a class file that implements the business logic basic.php

The test definition exposes classes class MYWSDL {    private $nombre = ';    Public function __construct ($name = ' world ') {$this->name = $name;}    Public function greet ($name = ") {$name = $name? $name: $this->name;        Return ' Hello '. $name. '. ';}    Public Function Servertimestamp () {return time ();} Public Function myfunc ($a = ") {    $arr = array (' a ' = = $a, ' b ' = = $a, ' c ' = = $a);        Return Json_encode ($arr);}}

A class that returns a string. Suppose this program is above server A, what if you want to call this program on Server B? First, we need to make this Class A Web service, which requires the SOAP extension of the previous PHP.

To create a service server.php, you need to use the SoapDiscovery.class.php file

Require_once (' basic.php ');//define (' Wsdl_url ', ' hello.wsdl ');        Defines the WSDL file path Ini_set (' soap.wsdl_cache_enabled ', ' 0 ');  automatically create if (!file_exists (' mywsdl.wsdl ') {    require_once ' SoapDiscovery.class.php ') when the WSDL cache//wsdl file does not exist;    $disco = new Soapdiscovery (' mywsdl ', ' www.zhuoqu.com ');    

OK, a Web service is set up, in the example above, we created a SoapServer object, and after that, we use the SetClass function to put the basic class that we just wrote in, and finally handle (). Now if you use a browser to access this file, a warning will appear, which is normal, because the file is not accessed by the browser, but is accessed by another program. When a client program accesses our webservice, running to handle () will process the client input and output the results to the client, where it is important to note that you do not output anything before and after handle (), and the client will not be able to handle it.

Now, write client access to our WebService

　

$client = new SoapClient ("http://127.0.0.1/s.php?wsdl"), try {$result = $client->myfunc (' 789 '); Var_dump (Json_ Decode ($result)); echo "The answer is result";} catch (SoapFault $e) {echo "Error Message: {$e->getmessage ()}";}

So we can access the client files to get the results we need.

SoapDiscovery.class.php file
