特定アプリのapp storeでのランキングを取得する

Posted at

アプリのランキングを取得するスクリプトを書いてみました。

<?php

$targetAppIds = array(
  'id834802911',
  'id443904275',
);

$feed = file_get_contents('https://itunes.apple.com/jp/rss/topfreeapplications/limit=100/xml');
$rss = simplexml_load_string($feed);

$result = array();

foreach($rss->entry as $val) {
    $ranking++;

    $title = $val->title;
    $url   = $val->id;

    foreach ($targetAppIds as $targetUrl) {
    if (strpos($url, $targetUrl) !== false) {
        $result[] = array(
            'app_name' => (string)$title,
            'ranking' => $ranking);
    }
    }
}

foreach ($result as $val) {
    echo sprintf("【%s位】%s\n", $val['ranking'], $val['app_name']);
}
