Question

在我的PHP应用程序中，我目前有两个类，一个可以搜索google places api附近的结果，另一个可以从api地方引用中获取详细信息。

我将来自附近搜索的20个结果返回到google places api，然后循环结果并将每个引用传递到获取地点详细信息api响应的类中。

我遇到的问题是它很慢，有没有办法加速这个过程，也许是对api的并发请求？

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;

您可以减少所做的API调用次数。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结果。如果可以缓存结果，您可以尝试。我不是Google Places API的专家，但也许您可以通过一次API调用而不是二十次来获取结果。 API调用的数量是您的性能问题。
