No, there aren't any that affect normal global variables.
Post a short example demonstrating your problem. Cut it down as far as you
can, so it's still runnable but shows the issue. (Often this process helps you
find the problem yourself).
Are you doing something like:
<?php
$myvariable = 'x';
echo $myvariable;
function f()
{
global $myvariable;
echo $myvariable;
}
?>
Does this not give the expected result on your system?
