Source code Bug or Feature?

[Bruce A. Julseth]

I have just inherited someone elses PHP code and there is something strange
in it, at least to me. I'm wondering if I inherited a source code bug or is
it a PHP feature that I don't know about. This code is in "index.htm" and
the first few lines of the file look like:

<?
if($parm) {
more code
}
?>

Now, the error I am getting is that "$parm" is not defined. I would expect
that. Or is there some "hidden" way $parm can be defined and I just haven't
found the code that does it, or don't how to do it.

Thanks...

Search for "register_globa ls", then correct the script to use $_GET or $_POST
and never think about register_global s being on again :-)

And use long opening tags: <?php
or you'll get in trouble with different configs or x(ht)ml docs.

RE: register_global s. I assume if I don't find any "register_globa ls"
defined, this is a bug in the code. Right?

Thanks...

: RE: register_global s. I assume if I don't find any "register_globa ls"
: defined, this is a bug in the code. Right?

It's a config setting in php.ini which is used by the server to control
how php works.

google: register_global s php_

Various entries, 'fraid you'll need to read a few to learn everything you
want to know.
