通过与php的相关性来命令json结果（similar_text）

Question

我正在使用soundcloud上的音乐搜索系统，我设法用 similar_text php函数显示每个结果的相关性。

现在我需要在订单中按照＆＃34; rating＆＃34;

排序结果

使用 similar_text 函数生成评级值，与搜索查询

进行比较

这是我的字符串（json响应）。

我需要将结果从最高到最低等级排序 这是我的json解码：

                            $content = $this->get($url);
                            $content = json_decode(substr(substr($content, 0, -2), 1));
                            if(empty($content)) break;
                            foreach ($content as $value) {
                                $id = $this->filterID($value->waveform_url, 'soundcloud');
//                                $download_url = 'http://media.soundcloud.com/stream/'.$download_url.'.mp3';
                                $titulo = $this->fixTitle($value->title);
                                similar_text($this->query, $titulo, $p);

                                //if(strpos($titulo, "emix") OR strpos($titulo, "dj ") OR strpos($titulo, "Dj ") )continue;
                                $this->tmp[] = array(
                                                'title'     => $this->fixTitle($value->title),
                                                'server'    => $key,
                                                'id'        => $id,
                                                'rating'    => $p,
                                                'download'  => 'request',
                                                'size'      => $this->formatBytes($value->original_content_size),
                                                'duration'  => $this->formatMilisecons($value->duration)
                                            );
                            }
