Implementation of the SOAP server - server.php:
<?php
// turn off WSDL caching
ini_set("soap.wsdl_cache_enabled","0");
// model, which uses in web service functions as parameter
class Book
{
public $name;
public $year;
}
/**
* Determines published year of the book by name.
* @param Book $book book instance with name set.
* @return int published year of the book or 0 if not found.
*/
function bookYear($book)
{
// list of the books
$_books=[
['name'=>'test 1','year'=>2011],
['name'=>'test 2','year'=>2012],
['name'=>'test 3','year'=>2013],
];
// search book by name
foreach($_books as $bk)
if($bk['name']==$book->name)
return $bk['year']; // book found
return 0; // book not found
}
// initialize SOAP Server
$server=new SoapServer("test.wsdl",[
'classmap'=>[
'book'=>'Book', // 'book' complex type in WSDL file mapped to the Book PHP class
]
]);
// register available functions
$server->addFunction('bookYear');
// start handling requests
$server->handle();Implementation of the SOAP client - client.php:
<?php
// model
class Book
{
public $name;
public $year;
}
// create instance and set a book name
$book =new Book();
$book->name='test 2';
// initialize SOAP client and call web service function
$client=new SoapClient('http://a.uz/soap/server.php?wsdl',['trace'=>1,'cache_wsdl'=>WSDL_CACHE_NONE]);
$resp =$client->bookYear($book);
// dump response
var_dump($resp);Dump of the response:
string '2012' (length=4)
