我最近学习MVC。我尝试在 MVC 结构中重新构建我的网站，并且在不同的名称空间内调用函数时遇到问题（也许我不太了解 OOP）。这是我的代码：

namespace UserFrosting;

class GroupController extends \UserFrosting\BaseController {

    public function testFunction($params){
        //Simple test function that i had error: Call to undefined function UserFrosting\testFunction()
        $params['Password'] = $pw;
        $params['JSON'] = 'Yes';
        $curl = curl_init($url);
        curl_setopt($curl, CURLOPT_POST, true);
        curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($params));
        curl_setopt($curl, CURLOPT_TIMEOUT, 30);
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); 
        curl_setopt($curl, CURLOPT_VERBOSE, true);
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
        $response = curl_exec($curl);
        if (curl_errno($curl)) $obj = (object) array('Result' => 'Error', 'Error' =>      curl_error($curl)); 
        else if (empty($response)) $obj = (object) array('Result' => 'Error', 'Error' => 'Connection failed'); 
        else $obj = json_decode($response);
        curl_close($curl);
        return $obj;
    }  

    public function loginNumber(){
        $params = array("Command" => "SystemStats");
        $api = testFunction($params);
        echo "<h3>Server Status</h3>\r\n";
        if ($api -> Result == "Error") die("Error: " . $api -> Error);
        echo "Logins: " . $api -> Logins . "<br/>\r\n";   
   }
}

所以基本上我打电话loginNumber()，然后它显示这个错误：*调用未定义的函数UserFrosting\testFunction()*

我遇到了同样的问题，SoupClient但我显示了这个错误：* Class 'UserFrosting\SoapClient' not found* 这是我soapClient在同名空间中的代码：

 public function templatePost(){

     $client = SoapClient('https://www.test.com/pg/services/WebGate/wsdl', ['encoding' => 'UTF-8']);

     $result = $client->PaymentRequest([
        'MerchantID'     => $MerchantID,
        'Amount'         => $Amount,
        'Description'    => $Description,
        'Email'          => $Email,
        'Mobile'         => $Mobile,
        'CallbackURL'    => $CallbackURL,
     ]);

     if ($result->Status == 100) {
        header('Location: https://www.test.com/pg/StartPay/'.$result->Authority);
     } else {
        echo'ERR: '.$result->Status;
     }
}

我有同样的错误，我的问题是什么？我怎样才能调用这些函数？

解释：你没有​​函数testFunction，但是对象GroupController有一个方法testFuntion。所以你需要使用 $this->.. 因为你已经在那个类中了。您的 loginNumber 应为：

public function loginNumber(){
    $params = array("Command" => "SystemStats");
    $api = $this->testFunction($params);
    echo "<h3>Server Status</h3>\r\n";
    if ($api -> Result == "Error") die("Error: " . $api -> Error);
    echo "Logins: " . $api -> Logins . "<br/>\r\n";
}

在您的第二个问题中，您没有正确导入 SoapClient 类。请试试：

$client = \SoapClient(...);

这使用来自根命名空间的 SoapClient。
