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;

How does garbage collection work for PHP sessions?How does garbage collection work for PHP sessions?Apr 27, 2025 am 12:19 AM

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.

How can you trace session activity in PHP?How can you trace session activity in PHP?Apr 27, 2025 am 12:10 AM

How do you loop through all the values stored in a PHP session?How do you loop through all the values stored in a PHP session?Apr 26, 2025 am 12:06 AM

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.
