尝试使用zendsoap时找不到

我正在尝试使用zendframework/zend-soap库在PHP中编写SOAP服务器。这是我的目录结构：

|- app/
|- mySoapService.php
|- composer.json
|- composer.lock
|- vendor/


这是composer.json的内容：

{
"name": "my_soap_service","description": "This package is implementing a SOAP service.","type": "project","require": {
"zendframework/zend-soap": "^2.8"
},"require-dev": {
}
}


我在终端中输入了以下命令：

zeinab: ~/my_soap_server$ composer install

这是mySoapService.php的内容：

class MyClass {
/**
* @param integer $inputParam
* @return string
*/
public function method1($inputParam) {
return "This is your input: " . $inputParam . ".";
}
/**
* @param integer $inputParam1
* @param string $inputParam2
* @return float
*/
public function method2($inputParam1,$inputParam2) {
return "This is your inputs: " . $inputParam1 . " and " . $inputParam2 . ".";
}
}
$server = new Zend\Soap\Server(null,$options);
// Bind Class to Soap Server
$server->setClass('MyClass');
// Bind already initialized object to Soap Server
$server->setObject(new MyClass());
$server->handle();


但是当我尝试使用php mySoapService.php运行它时，出现此错误：

zeinab:~/my_soap_server$ php app/mySoapServer.php
PHP Warning: Module 'soap' already loaded in Unknown on line 0
PHP Fatal error: Uncaught Error: Class 'Zend\Soap\Server' not found in /home/zeinab/my_soap_server/app/mySoapServer.php:23
Stack trace:
#0 {main}
thrown in /home/zeinab/my_soap_server/app/mySoapServer.php on line 23


我还尝试将"zendframework/zend-soap": "^2.8"放在require的{​​{1}}和require-dev部分中，并重复该过程；发生了相同的结果。

似乎您忘记了添加作曲家的自动加载功能。告诉PHP在哪里可以找到要实例化的类是必要的。看看Composer's documentation，了解有关它的更多信息。

在文件的开头添加include __DIR__ . '/PATH/TO/VENDOR/FOLDER/autoload.php';。
