如何在Ionic 2中使用mysql

I am new to Ionic 2.I have to manipulate Mysql data base through wampserver.I find this article : Using PHP and MySQL with Ionic 2

Where should I save the two .php files ? in a specific folder in C:\wamp\www\ ?

private baseURI : string = "http://www.remote-site-address-here.suffix/";

should i replace the string by the URI of the local base ?

Any help is highly appreciated.

localhost won't work on this, so you have to put your router url (if you are on same network) or upload php files on any hosting service and link to that on

private baseURI : string = "http://<URL-WHERE-YOU-HAVE-UPLOADED-FILES>/";
