Global Includes?

What are they? Are they like includes - but you can use them remotely? If so, could you give me an example?

If not, how would I go about doing this:

Say I had 3 sites, www.a.com www.b.com www.c.com and I wanted all of them to have the same text for a variable, and I could edit it via one file.

Like an include, but for three sites.

Thanks,
Keagle

 

Ad those three site in a file
Say filename glopal.php
include("www.a.com");
include("www.a.com");
include("www.a.com");

And then add that file to the required file you want.

 

Thank you!

 

if you want them to read the variable inside the php file, your 3 domain have to run in the same server!

if you just need to read the output, you can use echo file_get_contents("http://domain.com/something.php");
