Even if you don't know _why_ it didn't work, you could at least state what
you _expected_ to see and what you _actually_ saw.

It would be helpful on your part if you had stated your problem clearly.

Absolutely.

Again, what you expected to happen, and what actually happened are usually
a good starting points.

I'm not sure about this, but I don't think it was possible in previous
versions PHP.

Because PHP registers the globals etc (if enabled) then starts working on
your code.
Anyway, regardless of whether or not it is possible to set
register_globals at run-time, your code would be better re-written as:
<?
if (ini_set("register_globals", "0") !== FALSE)
echo "ini_set success";
else
echo "ini_set failed";
?>
Because, if you RTFM, ini_set() will return the existing value of whatever
you're setting. Thus if register_globals was already disabled then your
original code would return "ini_set failed" everytime.
