在不同的命名空间php中调用函数

Question

我最近学习MVC。我试图在MVC结构中重建我的网站，我有一个问题，在不同的名称空间内调用函数(也许我不太了解OOP)。下面是我的代码:

namespace UserFrosting;
class GroupController extends UserFrostingBaseController {
    public function testFunction($params){
        //Simple test function that i had error: Call to undefined function UserFrostingtestFunction()
        $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>rn";
        if ($api -> Result == "Error") die("Error: " . $api -> Error);
        echo "Logins: " . $api -> Logins . "<br/>rn";   
   }
}

基本上我调用了loginNumber()，然后它显示了这个错误:*调用未定义函数UserFrostingtestFunction()*

我有同样的问题与SoupClient，但它显示这个错误:*类"UserFrostingSoapClient"未找到*这是我的soapClient代码在同一名称空间:

 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?如何调用这些函数?

Answer 1

说明:没有testFunction函数，但是对象GroupController有一个testFunction方法。所以你需要使用$this->..因为你已经在那个类里了。你的loginNumber应该是:

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

在您的第二个问题中，您没有正确导入SoapClient类。请尝试:

$client = SoapClient(...);
