I suggest you to use
XAMPP
I also wanted to host a website from my computer.
Someone suggested me EasyPHP, but I couldn't get it work...
Then, someone else suggested me XAMPP and it worked like a charm
Read the whole thread here:
Installing PHP + MySQL on a windows machine?
I dont know, EasyPHP may work for you
I suggest you to download the installer version and not the 7-ZIP archive
Downsides:
Big file size (25 MB)
Takes some time to install
