Question

我正在使用nusoap库在php中编写一个Web服务。我可以返回简单的变量，如字符串，整数，也只返回一个复杂类型，即struct。但我无法返回结构数组。我在一周内研究了几乎所有关于此的例子，但它不起作用。那么我哪里出错？

代码

$server->wsdl->addComplexType('userSitesData','complexType','struct','all','',
        array(
                'id' => array('name'=>'id','type'=>'xsd:int'),
                'siteName' => array('name'=>'siteName','type'=>'xsd:string'),
                'workPlace' => array('name'=>'workPlace','type'=>'xsd:string'),
                'situation' => array('name'=>'situation','type'=>'xsd:string')
        )
);
// *************************************************************************

通过查看代码，

不需要第三种复杂类型“ UserSiteList”。您也可以使用以下方式将元素附加到$ myList数组中：

array_push($myList,$list); //inside while loop

请参考以下示例代码，该示例代码返回Employee结构的数组，

<?php

require_once "lib/nusoap.php";

function getEmployees($city){

    error_reporting(E_ALL & ~E_NOTICE);

    $arrayOfEmployees = array();

    $employeeArray1 = array();
    $employeeArray1['ID'] = 1;
    $employeeArray1['NAME'] = "Robert";
    $employeeArray1['City'] = "Newyork";
    array_push($arrayOfEmployees,$employeeArray1);

    $employeeArray2 = array();
    $employeeArray2['ID'] = 2;
    $employeeArray2['NAME'] = "Micheal";
    $employeeArray2['City'] = "Newyork";
    array_push($arrayOfEmployees,$employeeArray2);

    $employeeArray3 = array();
    $employeeArray3['ID'] = 3;
    $employeeArray3['NAME'] = "David";
    $employeeArray3['City'] = "Washington";
    array_push($arrayOfEmployees,$employeeArray3);

    $employeeArray4 = array();
    $employeeArray4['ID'] = 3;
    $employeeArray4['NAME'] = "Andy";
    $employeeArray4['City'] = "Newyork";
    array_push($arrayOfEmployees,$employeeArray4);

    //filter employees by city
    foreach($arrayOfEmployees as $elementKey => $element) {
    foreach($element as $valueKey => $value) {
        if($valueKey == 'City' && $value != $city){
            unset($arrayOfEmployees[$elementKey]);
        } 
    }
}


    return $arrayOfEmployees;

}

$server = new soap_server();
$namespace = 'http://localhost/test_soap_service/get_employee_list.php?WSDL';
$server->configureWSDL('GetEmployeesService', $namespace);

//create a complex type for Employee
$server->wsdl->addComplexType('Employee','complexType','struct','all','',
array(
'ID' => array('name' => 'ID','type' => 'xsd:int'),
'NAME' => array('name' => 'NAME','type' => 'xsd:string'),
'Age' => array('name' => 'Age','type' => 'xsd:int')
    )
);

//create a complex type for Array of Employees
$server->wsdl->addComplexType(
    'arrayOfEmployees',
    'complexType',
    'array',
    '',
    'SOAP-ENC:Array',
    array(),
    array(
        array(
            'ref' => 'SOAP-ENC:arrayType',
            'wsdl:arrayType' => 'tns:Employee[]'
        )
    )

);


$server->register("getEmployees",
    array('city' => 'xsd:string'),
    array('return' => 'tns:arrayOfEmployees')
    );

if ( !isset( $HTTP_RAW_POST_DATA ) ) $HTTP_RAW_POST_DATA =file_get_contents( 'php://input' );
$server->service($HTTP_RAW_POST_DATA);

?>

如何在PHP中使用Nusoap complextype返回嵌套数组？
