Scrap data from a webpage using selenium or simple html dom library > php

I know php and I am currently working on a php script to fetch data from this webpage [login to view URL] I am able to fetch data for Mar'17 to Mar'13 ( total income from operations- i only need this) on front page using php and simple html dom But unable to fetch data from Mar'12 to Mar'08 on next page (click on "Previous Years"). This is because in order to fetch data from next page the knowledge of selenium is needed. The next page can be visited only by calling a javascript function through the hyperlink click on "Previous Years". <a href="javascript:void()"> One need to click on this link to go to next page and this is not possible by simple html dom method which is server side scripting. The only thing I want you to do is to use "selenium" in my existing php script to simply click this javascript link and then let me know how to fetch data (only total income from operations needed) from the next page (from Mar'12 to Mar'08) using simple html dom again. Let me know if this is possible or you have any more ideas.
