Google放置API请求多个细节JSON页面

Question

在我的PHP应用程序中，我目前有两个类，一个可以从谷歌的地方api搜索附近的结果，一个可以从api的地方引用获得详细信息。

我从一个nearbysearch返回20个结果到google places api，然后在结果上循环，并将每个引用传递到获得地点细节api响应的类。

我遇到的问题是它很慢，有没有办法加速这个过程，也许并发请求的api?

foreach($results['results'] as $result) {
    $namenospace = str_replace(' ', '_', $result['name']);
        $details = new placedetail($apiKey, $result['reference']);
        $placedetails = $details->getdetails();
        if($placedetails['result']['website']) {
            $website = $placedetails['result']['website'];
            $name = '<a href="'.$website.'" >'.$result['name'].'</a>';
        } else {
            $name =     $result['name'];
        }
        $html .= '<li class="restaurantoption dontsplit">';
        $html .=     '<input type="checkbox" class="restaurantcheckbox" name="restaurant[]" value="'.$result['name'].'" checked /><span class="resaurantname" >'.$name.'</span><br/>';
        $html .= '<div class="vicinity" ><small>'.$result['vicinity'].'</small></div>';
        $html .= '</li>';
}
    echo $html;

您可以减少API调用的数量。也许一个选项是只获取一个结果，并在用户点击时预取其余的结果。如果缓存结果是可能的，您可以尝试一下。我不是Google places API的专家，但也许您可以通过一次API调用而不是20次调用来获取结果。API调用的数量是你的性能问题。
