REST,API and Php for searching online with android app
<p>I have an android app I accept a keyword to be searched,And I want to search ebay (an example) like searching for "Samsung S3" and displaying the values back in my app
I dont know how to go about this,Ive been told about REST,Php and APIs</p>

<p>Do I need to communicate with the database since Im not adding anything
And is there a way to make an API only in php,not using REST</p>

<p>I really have no experience of this..Im not trying to solicit a debate,I just want a very simple answer.So I will know which aspect I will start with.Thanks for ur support in advance</p>
