Getting error after I changed my pages from .html to .php

[DARK_BYTE]

Hi I am working on a project and had to change all my .html pages to .php since I had to call some php scripts in my pages.
For example on 1 page "macbook.html" I called "text01.php" which is a script that fetches text from a database and displays the text:

<img src="display01.php"/>

Now I have another page named macs.html that had a link like this:

<a href="macbook.html"><img src="product-white-hero2.jpg" alt="MacBook pic"/></a>
<br/>
<a class="nav" href="macbook.html">MacBook</a>

so to be able to call the "text01.php" I had to change the extension to macbook.php and since I had similar situations on almost all my files I changed all my .html to .php.
But now when I open phpmyadmin and browse to the 100% correct location and open the file index.php it shows me the first page with everything over there working but when I click on any other previously working link(before I changed everything to.php" it gives me this error:

Object not found!

The requested URL was not found on this server. If you entered the URL manually please check your spelling and try again.

If you think this is a server error, please contact the webmaster.
Error 404

Can someone please help me?

instead of changing the file names, you can have the *.html files parse php

create a file called .htaccess in your public_html (or what ever its called dir

add to the file:

RemoveHandler .html .htm
AddType application/x-httpd-php .php .htm .html

that will work in most situations.
