I have a number of fundraising web sites that are related but separate. They all share a database on the same server. For example, the candle site will query the candle fundraising information. The discount site will query the discount fundraising information.

Each of the sites use the same functions to call information from a database. I just pass different values to the functions to query the correct information. However, each site has its own function php page (included) which means when I update a function on one site, I have to do it on all of them. I'd like to have them all be able to include the functions from one master function page.

Can I use a php include statement to include pages from another domain?

For example:

If they are they on the same host/server then yes. If not try file_get_contents.

I participate on a PHP board and after posting here I thought I'd ask them too to get some extra input. This is a key response for me.


I don't think I'll pursue this idea. I'll find another way.

Are the files on the same host?

Yes

Then there should be no problem. I have some php scripts that reach up above the root of the site to keep files secure.

Can you share the coding that allows you to reach out beyond the folder where the site exists?

Here's a quick example.
