php - 从 url 获取 itunes id

Question

从 iTunes 应用程序链接检索 ID 的最佳方法是什么？

假设我有这些链接:

http://itunes.apple.com/us/app/bring-me-sandwiches!!/id457603026?mt=8

http://itunes.apple.com/us/app/bring-me-sandwiches!!/id457603026

我只想使用 php preg_match 获取 id，457603026

Answer 1

没有 preg_match:

$url = 'http://itunes.apple.com/us/app/bring-me-sandwiches!!/id457603026?mt=8';
echo end(explode('/id', parse_url($url, PHP_URL_PATH)));

或者，如果您愿意:

$url = 'http://itunes.apple.com/us/app/bring-me-sandwiches!!/id457603026?mt=8';
$id = explode('/id', parse_url($url, PHP_URL_PATH));
echo $id[1];
