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.
