variables not recognised

[windandwaves]

Hi Folk

I loaded a website onto a new webserver (from some ISP that I know little
about and I noticed that even though everything seemed to be working fine,
it does not actually recognise variables.

usually, if I have http://www.myurl.com/index.php?x=1 then $x == 1 in my
php file. However, on this ISP it sure did not do this.

Is this
a. an old version of PHP
b. a security feature
c. something else or had to know

TIA

My guess is that your code relies on register globals being enabled. Since
PHP 4.2 this directive is disabled by default, so $x should be referenced as
$_GET['x'].

Thank you, right on the ball! I have asked them if I can change the php.ini
file and I am using $_GET for now.

Thank you .

If I were you I'd try to rewrite things without using register globals
(i.e. using $_GET and $_POST). While it isn't a security risk in and
of itself, register globals does make it easier to write vulnerable
code.

Besides, if you write your site without relying on register globals, it
will run on a host with or without it. On the other hand, if you write
it using register globals, the site won't work without it.
