variable issues using includes

$variable="blah";
include("file.php"); ?>

Code (markup):

this works, allowing the included file to use the variable $variable

but, I changed my include path to another directory:

$variable="blah";
include("http://www.site.com/directory/file.php"); ?>

Code (markup):

and it no longer works....$variable isn't recongized.

Could this be resolved, and how can I refer to other folders above the current directory using a local path not using http://

 

Is this for security reasons?

 

this is a long shot, but try

include '/directory/file.php';

or

include 'directory/file.php';

I think, in general, if file.php is not in your server, you CANNOT do it. Because when you request a PHP file from an URL, the server will process that file and return the output.
If I am not right, so I can easily hack other site by

inlcude("http://www.theirserver.com/include.inc.php")

PHP:

 

Is this correct? I have this issue here:

and this answer might solve my problem. But isn't there a better way to include output from a different page? I basically ned to scrape a file's output.

 

$pageData = file_get_contents('http://www.feedsfarm.com/');

This will get the output of the page.

 

I think that's correct. However, if your file's extension is not .PHP, that may works.

 

oh, even more help in case i want to see some variables.

I forgot to mention that shawn's solution did work, just use a local path.
