在第 78 行出现 php 致命错误函数名称必须是 C:\wamp\www\drupal-7.42\sites\all\modules\form_fun\form_fun.cake.inc 中的字符串

Question

我正在尝试使用 drupal.But 向 moodle 发送一个 curl 请求，每个时间我运行这个代码我收到一条错误消息，函数名称必须是 string.I 已经尝试了一切但什么都没有 working.Can 有人帮帮我吗？

    function form_fun_cake_submit(&$form, &$form_state) {        
         $serverUrl=' http://localhost/moodle/my/webservice/rest/server.php?wstoken=d90b5d90db13711d12df525366f15db1';

     $functionName = 'core_user_create_users';
            $user1 = new stdClass();
            $user1->username = 'testusername1';
            $user1->password = 'Uk3@0d5w';
            $user1->firstname = 'testfirstname1';
            $user1->lastname = 'testlastname1';
            $user1->email = 'testemail1@moodle.com';
            $user1->auth = 'manual';
            $user1->idnumber = '';
            $user1->lang = 'en';
            $user1->timezone = 'Australia/Sydney';
            $user1->mailformat = 0;
            $user1->description = '';
            $user1->city = '';
            $user1->country = 'AU';     //list of abrevations is in yourmoodle/lang/en/countries
            $preferencename1 = 'auth_forcepasswordchange';
            $user1->preferences = array(
                array('type' => $preferencename1, 'value' => 'true')
                );

            $users = array($user1);
            $params = array('users' => $users);

            /// REST CALL
    $rest_format = 'json';

        //$server_url = $domain_name . '/webservice/rest/server.php' . '?wstoken=' . $token . '&wsfunction=' . $function_name;
        $server_url = 'localhost/moodle/my' . '/webservice/rest/server.php'. '?wstoken=' . '15bd45a3dab2958b7e8fc237b14f76cd' .'&wsfunction='. $functionName;
        dpm($server_url);
        require_once('curl.inc');
        $curl = new curl;
        $rest_format = ($rest_format == 'json') ? '&moodlewsrestformat=' . $rest_format : '';

  $resp =$curl($server_url . $rest_format, $params); //This is my line no 78
        dpm($rest_format);
        $respRc = json_decode($resp, true);




            dpm($resp);


            echo '</br>************************** Server Response    createUser()**************************</br></br>';
            echo $server_url . '</br></br>';

            var_dump($resp);




    }

第 78 行将 $curl(...) 替换为 new curl(..)，您的对象实例化不正确。告诉 php 日志的是，您正在使用一个变量作为函数名称，又名 $curl（与 $functionName 无关，如果错误，稍后可能会生成错误，而 curl 不会编译）。

$resp = new curl($server_url . $rest_format, $params);

在第 78 行出现 php 致命错误函数名称必须是 C:\wamp\www\drupal-7.42\sites\all\modules\form_fun\form_fun.cake.inc 中的字符串
