Passing Variable to Includes

[Anon]

I have a page that has a couple of includes in it. I am having trouble passing variables from the url to the include.

The include is called with $n=\"http://www.mysite.com/Folder/Includes/Navigation/index.php4?\".\"return=\".$return;
include ($n);

Neither the value of $return, or any of the other data that is usable within the rest of the page in which the include exists, is accessible within the include.

Can anyone tell me why this doesn\'t work or how to pass the variable to the include. I am deliberately not using cookies or sessions.

Thanks

You should not have to pass the value of $return in the include(). To quote the manual:

"[any] variable set in the scope in which the inclusion happens will be available within the included file automatically, since it has effectively become a part of the calling file."

Hence, if you set a variable:

$myVar = 28;

and then include a file:

include('incScript.inc');

then $myVar can be referenced and used anywhere within the included script, however; keep in mind that all scoping rules are still in affect. If your included file has function definitions and wants to use $myVar then you have to pass it into the function or define it within the function as GLOBAL.

you can pass a variable by setting its value before your include statement

say we have this file:

myinclude.inc:

<?php
print $foo
?>

to pass the variable do this:
$foo = 'bar';
include('./myinclude.inc');

and it will print
bar
