Erwin
If his basic requirement is to make variables from including file
available in included file, then surely any variable that's set in the
including file before the include occurs will be available to the
included code?
eg:
includer.php:
<?php
// including file
$value = "text";
include "included.php";
?>
included.php:
<?php
if (!isset($value)) $value="\$value was not set";
echo $value . "\n";
?>
and testing:
$php includer.php
text
$
although it would probably be a good idea to use:
if (!isset($var)) $var=default_value;
in included.php for every expected var.
