Why does the script not work on the hosting, but works on the local?

Question

PHP

In short, I have a website and it has a player with an online radio station stream. I wanted to add data about the playing track on the air to the player and for this I went to the hosting site for broadcasting on IceCast 2 (radioheart.ru). There was a script on their site to get data about the playing track, which I took. Having written the code on the local, everything worked perfectly (there were no errors) and the playing track was shown, but when the script was transferred to the hosting (I use hoster.kz), the script stopped working.

Script with the technique of adding to the site:

Create a radiostat.php file, add the following code to it and save it in the root of the site:

<?php
                            //НАСТРОЙКИ СКРИПТА//
                            //Ссылка на картинку, которая будет отображаться, если изображение не найдено в базе LAST.FM
                            $no_photo_url='http://upload.wikimedia.org/wikipedia/commons/3/37/No_person.jpg';
                            $width='100'; //ширина картинки
                            $height='100';  //высота картинки
                            //НЕ ИЗМЕНЯЙТЕ НИЧЕГО НИЖЕ///
                            //LIVE STREAM
                            $data = json_decode(file_get_contents("http://s0.radioheart.ru:8000/json.xsl?mount=/radioart"));
                            if (!count($data->mounts) || strlen($data->mounts[0]->server_name) < 2) {
                                //NONSTOP
                                $data = json_decode(file_get_contents("http://s0.radioheart.ru:8000/json.xsl?mount=/nonstop"));
                            }
                            $stream_title = $data->mounts[0]->server_name;
                            //Если сайт в кодировке windows-1251 (cp-1251), раскомментируйте следующую строчку
                            //$stream_title = iconv("UTF-8", "WINDOWS-1251", $stream_title);
                            $stream_description = $data->mounts[0]->description;
                            $listeners = $data->mounts[0]->listeners;
                            $song = $data->mounts[0]->title;
                            $image = '';
                            //Если сайт в кодировке windows-1251 (cp-1251), раскомментируйте следующую строчку
                            //$song = iconv("UTF-8", "WINDOWS-1251", $song);
                            $artist = explode(" - ", $song);
                            $artist = $artist[0];
                            $artist = str_replace(" ", " ", $artist);
                            $size = "large";
                                                        // Выводим данные
                            echo "<div id='radiostat'>";
                            
                            echo "Название потока: $stream_title<br />";
                                                        
                            echo "Описание потока: $stream_description<br />";
                                                        
                            echo "Слушателей: $listeners<br />";
                                                        
                            echo "Сейчас в эфире: $song<br />";
                                                        
                            echo "</div>";
                            
                            ?>

We add a container on the site where the information should be displayed: Connect the Jquery library between the and tags, if you don't have it already!

<div id="radiostat">Загрузка...</div>

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>

We insert between tags and in the site code after connecting Jquery

<script>
                            function nowplay()
                            {
                                $.ajax({
                                    url: "/radiostat.php",  //Тут указываем файл со скриптами
                                    cache: false,
                                    success: function(html){
                                        $("#radiostat").html(html); //Контейнер для вывода информации
                                    }
                                });
                            }

                            $(document).ready(function(){
                                nowplay();
                                setInterval('nowplay()',30000);  //Время в милесекундах, 30000=30сек
                            });
                        </script>

Answer 1

what does file_get_contents(" s0.radioheart.ru:8000/json.xsl?mount=/radioart ") return?
maybe file_get_contents on hosting is limited
