php如何调用.net的webservice???100分送上
php如何调用.net的webservice?请高手赐教,我写了一面一段程序,可是总是提示错误:没有创建实例对象,大家帮我看一下,哪里错了?
客户端php程序:
require('./require/nusoap/lib/nusoap.php');
$userinfo=array('username' => 'fiekscos');
$s=new soapclient('http://www.yy-sports.com/webservice/memberinfo.asmx?WSDL');
$s->soap_defencoding = 'UTF-8';
$s->decode_utf8 = false;
$result = $s->__soapCall('ValidUserLoginName',array('UserLoginName' => $userinfo));
echo $result;
?>
服务器端.net的webservice程序:

using System.Collections;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;
using com.Basic;
///

// [System.Web.Script.Services.ScriptService]
public class MemberInfo : System.Web.Services.WebService
{

/// SOAP认证类

public SecurityHeader CurrentUser
{
get { return _CurrentUser; }
set { _CurrentUser = value; }
}
private SecurityHeader _CurrentUser;
public MemberInfo()
{
//如果使用设计的组件,请取消注释以下行
//InitializeComponent();
}
private bool ValidateUser(string user, string pass)
{
Boolean reVal=false;
EDbOperator oo = new EDbOperator();
try
{
String sql = "Select Count([ID]) From WebService_User Where [Name]='{0}' And Pass='{1}' And [Status] = 1";
user = Tools.FilterSQL(user.Trim());
pass = Tools.FilterSQL(pass.Trim());
sql = String.Format(sql, user, pass);
Int32 Count = Convert.ToInt32(oo.DbOperator.ExecScalar(sql));
if (Count > 0)
{
reVal = true;
}
}
finally
{
oo.Dispose();
}
return reVal;
}
///
/// 根据系列代码,返回系列名称

Int32 reVal = 1;

Arrays can be stored in PHP sessions. 1. Start the session and use session_start(). 2. Create an array and store it in $_SESSION. 3. Retrieve the array through $_SESSION. 4. Optimize session data to improve performance.

PHP session garbage collection is triggered through a probability mechanism to clean up expired session data. 1) Set the trigger probability and session life cycle in the configuration file; 2) You can use cron tasks to optimize high-load applications; 3) You need to balance the garbage collection frequency and performance to avoid data loss.

Tracking user session activities in PHP is implemented through session management. 1) Use session_start() to start the session. 2) Store and access data through the $_SESSION array. 3) Call session_destroy() to end the session. Session tracking is used for user behavior analysis, security monitoring, and performance optimization.

Using databases to store PHP session data can improve performance and scalability. 1) Configure MySQL to store session data: Set up the session processor in php.ini or PHP code. 2) Implement custom session processor: define open, close, read, write and other functions to interact with the database. 3) Optimization and best practices: Use indexing, caching, data compression and distributed storage to improve performance.

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

The session realizes user authentication through the server-side state management mechanism. 1) Session creation and generation of unique IDs, 2) IDs are passed through cookies, 3) Server stores and accesses session data through IDs, 4) User authentication and status management are realized, improving application security and user experience.
