Implementing soap using PHP

Falcon · #41 (**permalink**) 04-03-2008, 08:59 PM

Hi Buddies

Here is one simple example to create our own WSDL file

PHP Code:

  <?php # HelloServerWsdl.php

function hello($someone) { 

   return "Hello " . $someone . "! - With WSDL";

} 

   ini_set("soap.wsdl_cache_enabled", "0"); 

   $server = new SoapServer("http://localhost/Hello.wsdl",

      array('soap_version' => SOAP_1_2));

   $server->addFunction("hello"); 

   $server->handle(); 

?>

Hi Buddies

Above mention code will generate the following WSDL file

Code:

<?xml version="1.0"?>
<definitions name="MyDefinition"  targetNamespace="urn:myTargetNamespace" xmlns:tns="urn:myTns" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns="http://schemas.xmlsoap.org/wsdl/">
 <message name="myRequest">
  <part name="reqParam" type="xsd:string"/>
 </message>
 <message name="myResponse">
  <part name="resParam" type="xsd:string"/>
 </message>
 <portType name="MyPortType">
  <operation name="hello">
   <input message="tns:myRequest"/>
   <output message="tns:myResponse"/>
  </operation>
 </portType>
 <binding name="MyBinding" type="tns:MyPortType">
  <soap:binding style="rpc"
   transport="http://schemas.xmlsoap.org/soap/http"/>
  <operation name="hello">
   <soap:operation soapAction=""/>
   <input>
    <soap:body use="encoded"
     namespace="urn:myInputNamespace"
     encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
   </input>
   <output>
    <soap:body use="encoded"
     namespace="urn:myOutputNamespace"
     encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
   </output>
  </operation>
 </binding>
 <service name="MyService">
  <documentation>Returns a greeting string.
  </documentation>
  <port name="MyPort" binding="tns:MyBinding">
   <soap:address
  location="http://localhost/HelloServerWsdl.php"/>
  </port>
 </service>
</definitions>

Hi,
Here i wanted to create web services for my login component. How can i proceed?

Any idea?

Falcon · #44 (**permalink**) 04-04-2008, 11:37 PM

Hi

PHP Code:

  <?php # LoginServerWsdl.php

function login($username,$password) { 

   $aResultSet =  checkUser($vUsername,$vPassword);

   $vResult = $aResultSet['Result'];

   if($vResult >1)

   {

        session_register('sesID','sesName','sesTrackID','sesLastLogin');

    $_SESSION['sesID'] = $vID;

    $_SESSION['sesName'] = $vName;

    $_SESSION['sesTrackID'] = $vTrackID;

    $_SESSION['sesLastLogin'] = $vLastLogin;

   }

} 

   ini_set("soap.wsdl_cache_enabled", "0"); 

   $server = new SoapServer("http://localhost/login.wsdl",

      array('soap_version' => SOAP_1_2));

   $server->addFunction("login"); 

   $server->handle(); 

?>

I think this sample code will help you to create the login wsdl file for your site

Hi,
Thanks for the reply.
where can we actually place wsdl document file on web server for a new web service?

Falcon · #46 (**permalink**) 04-07-2008, 08:43 PM

Hi

You no need to give any particular location. You can place any where in your website. WSDL will placed in location as per your mention location while creating the object like $server = new SoapServer("http://localhost/login.wsdl", array('soap_version' => SOAP_1_2));

Hi,

Following steps are necessary to install the Apache soap Server

Download a version of Apache SOAP from the Apache XML pages. I downloaded the version 2.2 binary for these tests. You must use 2.2 or later to follow these instructions.
Unzip the downloaded file. I unzipped to j:\, which put everything in the j:\soap-2_2 directory.
Install Apache SOAP as a Tomcat Web application by running
- j:
- cd \jakarta-tomcat-4.0.1\bin
- shutdown
- cd \jakarta-tomcat-4.0.1\webapps
- mkdir soap
- cd soap
- jar -xvf j:\soap-2_2\webapps\soap.war
- cd \jakarta-tomcat-4.0.1\bin
- startup
Test that Apache SOAP is installed by pointing your browser to http://localhost:8080/soap/index.html. You should get a page saying "Hello! Welcome to Apache-SOAP."
Further test that Apache SOAP is installed by pointing your browser to http://localhost:8080/soap/servlet/rpcrouter. You should get a page saying "Sorry, I don't speak via HTTP GET- you have to use HTTP POST to talk to me."

Hi,
Thanks for the reply for installation on SOAP server.

How can SOAP application be differentiated with normal CURL functions?

Falcon · #51 (**permalink**) 04-15-2008, 09:06 PM

Hi

Curl function return all the content of the page in String but SOAP return only the particular content like only the search results in XML format. Second thing we have to explode the string to get URL,TITLE DESCRIPTION etc in CURL function but In SOAP they are gave all the details in separate tags it is easy to get that details

hi,
So CURL is any way have differed lot from SOAP.

While using with CURL, it is needed to have permission to read data from other servers?

Falcon · #53 (**permalink**) 04-17-2008, 05:24 AM

Hi

While using CURL functions,we no need to get permission to read data from other servers.For SOAP only we need permission from that particular server.It also depends up on the site and WSDL only

Regards
Falcon

Jeyaseelansarc · #54 (**permalink**) 04-17-2008, 07:55 AM

hi,
thanks for the reply. can we read the files if they set any permission for reading through CURL?

Falcon · #55 (**permalink**) 04-21-2008, 03:33 AM

Hi

If there are any authentication set for a page then we cant get the details of that page otherwise we can get the details of that page

Regards
Falcon

Jeyaseelansarc · #56 (**permalink**) 04-22-2008, 01:45 AM

Hi,
I think that is correct. I think we can get the HTML versions of the content via CURL functions. Am i right?

Falcon · #57 (**permalink**) 04-23-2008, 01:24 AM

Hi

Yes your are right that curl function tooks only the HTML version of that content. Its wont get the complete details. if a page is developed with the javascript Ajax functions. It wont get the content of that page.

Falcon · #59 (**permalink**) 05-02-2008, 03:54 AM

Hi

Here is one sample code for the Curl function

PHP Code:

  $vUrl="www.test.com";

$ch=curl_init();

curl_setopt($ch,CURLOPT_URL,$vUrl);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$this->content=curl_exec($ch);

curl_close($ch);
