If I have a URL similar to this:

How do I download the file using wget? Everytime I try I always end up downloading the php file.

The php file you downloaded with wget is actually a zip file with php extensions. Rename the file extension and you'll be able to extract the contents normally.

wget saves the file with the same name as the filename in the URL by default. To set the output name, see @bfhd`s comment.

For a case where you need to POST authentication information, you can do the following, which is extracted from StackOverflow: How to use wget post data

# Log in to the server.  This can be done only once.                   
wget --save-cookies cookies.txt \
     --post-data 'user=foo&password=bar' \

# Now grab the page or pages we care about.
wget --load-cookies cookies.txt \

You can also do "wget -O"; which will rename the file for you. – bfhd Oct 10 '11 at 0:14
