Re: Variable scoping - issues with global and multiple includes

argh! stupid gmail posting system that kills formatting !!!

Reformatted, here is my original query:

Hi All,

Sorry if I'm just repeating other questions, but I can't find an answer
for this particular problem:

I have my main index.php file, which looks so:

<?php

include "includes/header.php"; #defines a global variable called $lang

include "includes/functions.php"; # some required functions

safe_include "main_page.html "; # user-defined function that tries to

# include main_page.html. $lang or gives a
warning message

echo "Language available to index.php at line XYZ is -$lang-";

include "includes/footer.php"; #page footer

?>

and header.php looks so:
<?php
global $lang;
$lang = "en";
?>

footer.php looks like so:
<?php
echo "Language is set to -$lang-";
?>

Now the problem is, the $lang variable is available to all statements
in between, upto and including the safe_include statement.

Unfortunately, footer.php refuses to see the variable. What can be the
problem?

Thanks Hrishikesh

You must have unset it somewhere. Otherwise it would still exist.
