Where is the Zend "Application.php" in Dreamweaver???? Help ASAP

Question

Hi all, so I thought I knew enough to get me by in DW/coding. But I can't seem to figure out how Zend works, I've never used it. All I'm trying to do is edit some simple text on a webpage that my predecessor at my job set up. When I go to login to the site, the root directory has the images on the side and a file marked: index.php. It simply has this (see code below) with two .php files (Application.php and Autoloader.php) next to the source code that cannot be found. Do I really need to buy Zend Studio or something to be able to change her webpage? I don't want to and it seems silly that I can't edit a simple .html without going into their app but maybe I'm wrong and something can be fixed. I've been at this on and off for a week and my boss is at the precipice of getting angry with me.
As always thanks in advanced,
Mitch

Ya'll are going too fast for me to keep up... I'll try to answer and stay in the conversation as I work.
You say the website's setup like a person who did their very first website project in high school imo, but it sounds like you're actually the one working on their very first website project in high school and the website is setup for a scalable application where whoever did it knew what they were doing and set it up this way for a reason.
A fair point, and again I've already told my boss I do not work on Zend nor plan to until I'm comfortable working on it and am looking for a new job currently. But again, call it integrity, call it pride, I want to get these fixes done. Regardless of my future employment status, I'm here at work attempting to do stuff to the best of my ability. Since this is outside of my abilities, I'm seeking help for the edits at hand. The high school project comment was a little juvenile I'll admit, but I'm frustrated and I was making the point of how simple the website itself is.
The poster said his boss is non-technical and didn't say anything about ZFwhen he was hired and he never claimed to have that knowledge, so I think you are being way too hard on the poster.
I suspect that the company hired someone who had a strong skillset and built something that no one else inthe coompany understands. That person probably left the company with some bad blood, so no one knows what's going on with the webiste and the company does not understand the qualifications needed to take over the job.
That's not the poster's fault.
I asked my boss about it and he didn't know and when I logged onto our personal site for the first time, I saw it was a wordpress site which I know quite well (as do most people). Then there have been other sites I work on that are simple HTML without the ZF application code anywhere in it. There are two that run on magento, which I also know quite well. This one came up recently and I do not know it. First time I've run into Zend. As far as the man who I replaced, he had some animosity towards my boss. I've reached out to him a few times and he told me he wouldn't even deal with being a freelancer he can't stand it so much. So yes, I'm under qualified compared to him and yes I'm not a good fit, but I was the best he could get at such short notice for the amount he was asking. I'm young and inexperienced but I don't run away or resign from an issue.
