How to edit dynamic page

Learning how to code by editing an existing dynamic pages site that is live. Have a question on how to edit dynamic pages. For ex: I want to edit static text on a page. I can figure out stuff using firebug and seeing html, nodes, etc but I have no idea how to find the correct/relevant file on my server to edit and make changes the static text so something else. I see CSS files, js files. Is it a php file maybe? Where shou开发者_开发技巧ld I look? Maybe other files? Can't seem to figure out! Thanks for your help!

If the text comes out of a database/CMS, you'll have to search the database.

If the text is hard-coded in the code itself, use a search utility on that set of folders to find a match.

You can't always tell looking at the output on the client to determine the source unless you're familiar with the code.
