NuSoap

Here are my expirience in working with NuSoap (SOAP) in PHP.

Creating simple SOAP function is simple,  so there is no need to explain.

Problems are coming when you need a complex types, like array, and UTF-8 encoding.

Here is an example of adding complex type to your SOAP server:

$server->wsdl->addComplexType(
     'Chapter',     //name
     'complexType',  //typeClass (complexType|simpleType|attribut) 
     'struct',  //phpType: currently supported are array and struct (php assoc array)
     'all',  //compositor (all|sequence|choice)
     '',  //restrictionBase namespace:name (http://schemas.xmlsoap.org/soap/encoding/:Array)
     array(  //elements = array ( name = array(name=>”,type=>”) )
         'title' => array('name'=>'title','type'=>'xsd:string'),
         'page' => array('name'=>'page','type'=>'xsd:int')
     ) );
   $server->wsdl->addComplexType(
     'ChapterArray',
     'complexType',
     'array',
     '',
     'SOAP-ENC:Array',
     array(),
     array(
         array('ref'=>'SOAP-ENC:arrayType','wsdl:arrayType'=>'tns:Chapter[]')
     ),
     'tns:Chapter' );

   $server->wsdl->addComplexType(
     'Book',
     'complexType',
     'struct',
     'all',
     '',
     array(
         'author' => array('name'=>'author','type'=>'xsd:string'),
         'title' => array('name'=>'title','type'=>'xsd:string'),
         'numpages' => array('name'=>'numpages','type'=>'xsd:int'),
         'toc' => array('name'=>'toc','type'=>'tns:ChapterArray')
     ) ); 

$server->register(
    'getBook',  // method name
    array('title'=>'xsd:string'),  // input parameters    
    array('return'=>'tns:Book'), // output parameters
     $NAMESPACE); // namespace

function getBook($title) {
     // Create TOC
     $toc = array();
     $toc[] = array('title' => 'Chapter One', 'page' => 1);
     $toc[] = array('title' => 'Chapter Two', 'page' => 30);
  
     // Create book
     $book = array(
                 'author' => "Jack London",
                 'title' => $title,
                 'numpages' => 42,
                 'toc' => $toc);
  
     return $book;
}

Client example:

<?php
  require_once('nusoap.php');

  $namep = "Title";
  $param = array('String_1' => $namep);

  $endpoint = "http://localhost/server.php";

  $mynamespace = "http://localhost/server.php";
  $client = new soapclient($endpoint);

  $client->decodeUTF8 = true;
  $response = $client->call('getBook', $param, $mynamespace);
  print_r ($response['author']);
  echo '<p/>'.$client->response;
?>
 

Now, if you want to use utf - 8, you will have to in nusoap.php on line 152, instead of:

var $soap_defencoding = 'ISO-8859-1';

Add or uncomment:

var $soap_defencoding = 'UTF-8';

Also, on server side I added:

$server->decode_utf8  =  true; 

If you are using MySQL and data are encoded in Windows-1252 (like mine) then you will need to put:

mysql_query('set names utf8');

In  your server side.

I hope that is all.
