[尝试使用zend-soap时找不到

Question

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

我还试图将"zendframework/zend-soap": "^2.8"放在require的require-dev和composer.json部分中，然后重复该过程；发生了相同的结果。

似乎您忘了添加作曲家的自动加载功能。告诉PHP在哪里可以找到您要实例化的类是必要的。请查看Composer's documentation，以获取有关它的更多信息。

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