The above code is probably being included, and probably being included
by a function and so $foo does not have global scope. To ensure global
scope:
<?php
$GLOBALS['foo'] = 'bar';
function foobar()
{
global $foo;
print( " ------ " . $foo );
exit;
}
foobar();
?>
Try that and let us know what happend.
Cheers,
Rob.
