雅虎，谷歌，Yelp API

Question

是否有任何PHP API通过其来自Yelp，Google，Insiderpages，Yahoo的电话号码收集有关业务（地址，评论）的信息..请帮助，我已经对这些进行了研究，但没有得到正确的信息，虽然yelp通过它的电话号码提供信息但是他们要求ywsid作为mendatory（ http://api.yelp.com/phone_search?phone=1234567890&ywsid=XXXXXXXXXXXXXXXX ）但我只想通过电话号码。

Please note that all APIs have terms, most of them won't allow you to store their data in your own database and most of them have display requirements, before proceeding with any developing please read carefully their display requirements and terms.
Depending on your project you might not be allowed to use the data as you might need/want to on your project.
The other alternative would be scrapping sites, but most sites have rules against scraping too...
And again read a lot before putting too effort on something you are prohibited to in first place.

Yelp
ywsid = API key, you need to get your own key if you are using the yelp API, get it here
if you are using it to add it to your own database or storing the information anywhere it is against their policies display requirements & api terms .
if you are using any API you must read their terms before even thinking of doing anything.

Google Places
API

Insiderpages
I Don't think they have one but you could use the citygrid API that does a [lot of sites] search at once.

Yahoo
Yahoo API

CityGrid
As mentioned before citygrid API

Foursquare
Foursquare API

Merchant Circle
Merchant Circle API

White Pages
White Pages API

Yellow Pages
Yellow Pages API

Bottom line is, all these companies have put a lot of time and effort and money to build their databases, and they want you to redirect people back to their pages so they can make their money back/profit.
