问在foreach循环优化中使用curl？

EN

foreach($json as j){

    $id = $j->id; //from http://api.linke1.com/names

    $url = "https://api.site/{$id}/photos";
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    $output = curl_exec($ch);
    curl_close($ch);    

    $jsonDecode = json_decode($output);
    $results = $jsonDecode->results;
    foreach($results as $result)
    {   
            $photoURL= $result->photo->url; //from https://api.site/{$id}/photos
    }
}
