在 php 中循环访问 JSON 会减慢我的页面加载速度

我有一个小网站 jamesmcnee.co.uk，它的页面加载时间相当长。加载页面可能需要长达 8 - 12 秒的时间。我认为这与我创建的PHP有关，以便与Steam API进行交互。我有这些文件：

1. SteamWidget.php：

   $api = "http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?key=". $key ."&steamids=76561198014955377&format=json";
   $json = file_get_contents($api);
   $schemaProfile = json_decode($json, true);
   $api = "http://api.steampowered.com/IPlayerService/GetOwnedGames/v0001/?key=". $key ."&steamid=76561198014955377&format=json";
   $json = file_get_contents($api);
   $schemaGames = json_decode($json, true);
   echo '<div id="sideSteamProfile">';
   echo '<h2>On Steam</h2>';
   echo '<img src="'; echo $schemaProfile['response']['players'][0]['avatarfull']; echo '" alt="Steam Avatar Icon" />';
   echo '<p>Steam Name:<a href="'; echo $schemaProfile['response']['players'][0]['profileurl']; echo '">'; 
   echo $schemaProfile['response']['players'][0]['personaname']; echo '</a></p>';
   if($schemaProfile['response']['players'][0]['personastate'] == "0"){
           echo '<p>Currently: <font color="red">Offline</font></p>';
       }
       else{
           echo '<p>Currently: <font color="green">Online</font></p>';
       }       
   echo '<p>Last Online:'; echo gmdate("d-m-Y  H:i", $schemaProfile['response']['players'][0]['lastlogoff']); echo '</p>';
   echo '<p>Number of Games:'; echo $schemaGames['response']['game_count']; echo '</p>';
   echo '<p>Most Played Game:'; echo getMostPlayed(); echo '</p>';
   echo '<p>Total Hours:'; echo getHoursPlayed(); '</p>';
   echo '</div> <!-- Closes the sideSection div -->'; ?>
   

第二个叫做MostPlayed.php：

<?php 
    include 'ApiKey.php';
    function getMostPlayed()
    {
        $GameWithMostHours = "None";
        $api = "http://api.steampowered.com/IPlayerService/GetOwnedGames/v0001/?key=". $key ."&steamid=76561198014955377&format=json";
        $json = file_get_contents($api);
        $schemaGames = json_decode($json, true);
        $NumberOfGames = $schemaGames['response']['game_count'];
        $CurrentlyHighestHours = 0;
        for ($x = 0; $x < $NumberOfGames; $x++){
            $CheckHighest = $schemaGames['response']['games'][$x]['playtime_forever'];
            if ($CheckHighest > $CurrentlyHighestHours){
                $CurrentlyHighestHours = $CheckHighest;
                $GameWithMostHours = $schemaGames['response']['games'][$x]['name'];
            }
        }
        return $GameWithMostHours;
    }
    function getHoursPlayed()
    {
        $api = "http://api.steampowered.com/IPlayerService/GetOwnedGames/v0001/?key=". $key ."&steamid=76561198014955377&format=json";
        $json = file_get_contents($api);
        $schemaGames = json_decode($json, true);
        $NumberOfGames = $schemaGames['response']['game_count'];
        $TotalNumberOfHours = 0;
        for ($x = 0; $x < $NumberOfGames; $x++){
            $TotalNumberOfHours += $schemaGames['response']['games'][$x]['playtime_forever'];
        }
        $TotalNumberOfHours = sprintf("%02dh %02dm", floor($TotalNumberOfHours/60), $TotalNumberOfHours%60);
        return $TotalNumberOfHours;
    }
?>

所以两个简单的PHP文件，那么为什么要提高加载速度。正如我提到的，我认为这与我正在使用的 for 循环有关，但我看不到另一种方法可以做到这一点，并且在另一种语言（如 JAVA）中，这些循环需要几分之一秒。任何建议不胜感激！

谢谢詹姆斯·麦克尼。
