Question

我最近学习MVC。我尝试在MVC结构中反复我的网站，我有一个问题，在不同的名称sapace内调用函数（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给loginNumber()，然后它显示了这个错误：* 调用未定义的函数UserFrosting \ testFunction（）*

我遇到与SoupClient相同的问题但是我显示了这个错误：* Class＆＃39; UserFrosting \ SoapClient＆＃39;未找到* 这是我的soapClient代码，名称相同：

 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？我怎么称呼这些功能？

说明：您没有函数testFunction，但对象GroupController有一个方法testFuntion。因此，您需要使用$ this-＆gt; ..因为您已经在该类中。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";
}

在第二个问题中，您没有正确导入SoapClient类。请尝试：

$client = \SoapClient(...);

这使用了根命名空间中的SoapClient。

在不同的namespacs中调用一个函数php
