Howto get REMOTE ADDR if register globals = Off

[minibear]

I have a my.php script, it needs to included at the very PHP script my Vbulletin forum.

<IfModule mod_php5.c>
 php_value auto_prepend_file "/my.php"
</IfModule>

but this script can't get _SERVER["REMOTE_ADDR"], only if i tun register_globals = On

Hier is a test script. It can get $_SERVER['REMOTE_ADDR'] unter register_globals = Off.
if i type in browser:

http://mysite.com/test.php

why ?

test script:

<?php
$ip = $_SERVER['REMOTE_ADDR'];
echo '$ip';
?>

but if it run in schell

>php test.php

PHP Notice: Undefined index: REMOTE_ADDR in test.php on line 2

anyone knows, how to fix this problem.

but if it run in schell

Ah...there is no remote address when you run in a shell. That's why it is undefined.

[minibear]

you are right.
If i needs to includ my.php at the very PHP script my Vbulletin forum.
whichone should i use between

require_once('my.php');
and
<IfModule mod_php5.c>
php_value auto_prepend_file "/my.php"
</IfModule>

Which difference have them.

include(), require()

and the httpd-launched

auto_prepend_file

all work the same way:- they drop the contents of the referenced-file into your current file, just as if that file contained the code in the first place.

Therefore, it depends on how you call the original file:

• Call it from a shell script: no

  $_SERVER['REMOTE_ADDR']

  variable.
  
• Call it from a browser:

  $_SERVER['REMOTE_ADDR']

  variable supplied.
