如何使用 PHP 查找 iTunes 应用程序商店中应用程序的价格？
我将创建一个网站，要求某些 iPhone 应用程序提供最新价格，我知道这是可能的，因为 AppShopper 网站就是这样做的，只不过他们对每个网站都这样做。尽管我学得很快，但我对 PHP 的使用并不熟练。
我认为我需要创建一个蜘蛛/scraper来获取网站上的值，尽管我已经做了很多研究，但我还没有弄清楚，尽管我这可能不是我想要的需要。我对蜘蛛的创造并不熟悉，尽管我愿意学习。这不会是该网站的关键点，因此它不需要是最强大的系统，我只是希望能够更新价格，
我将不胜感激任何人提供的任何帮助或建议。
I am going to be creating a website which will require up-to-date prices on certain iPhone apps, which I know is possible because the website AppShopper does just that except they do it with every website. I am not that skilled using PHP though I am a quick learner.
I think that I will need to create a spider/scraper that takes the values from the website though I have done lots of research and I haven't figured it out, though I this may not be what I need. I am not familiar with the creation of spiders, though I am willing to learn. This will not be the key-point of the site so it doesn't need to be the most robust system, I would just like to be able to have it updated the prices
I would appreciate any help or suggestions that anyone has to offer.

Apple 提供了官方的搜索 API。我自己没有使用过，但值得研究一下。了解更多在这里。
There is an official Search API provided by Apple. I haven't used it myself, but it's worth looking into. Read more here.
