I did yesterday, hopefully, things go better now..

Sorry, my fault! This was one of my experiments to see why the $GLOBALS 
construction was not working with me. At first, I did try your original 
function, without any result though....

Yes, that works fine with me... I know this must work in php, but on
the other hand, why does the construction not work in the phpweather script 
I have.

Then I tried following, I changed your script to this:
  <html>
  <head>
    <title>PHP Weather</title>
  </head>
  <body>

  <?php

  function f($a) {
    $GLOBALS['foo'] = $a;
    printf("GLOBALS[] within function:  ".$GLOBALS['foo']."<br>");
    printf("foo within function      :  ".$foo."<br>");
  }

  function g() {
    printf("GLOBALS[] within other function:  ".$GLOBALS['foo']."<br>");
    printf("foo within other function      :  ".$foo."<br>");
  }

  f('Hello');

  printf("GLOBALS[] outside function: ".$GLOBALS['foo']."<br>");
  printf("foo outside function      : ".$foo."<br>");
  g();

  ?>
  </body>
  </html>

and this is what I got:

  GLOBALS[] within function: Hello
  foo within function :
  GLOBALS[] outside function: Hello
  foo outside function : Hello
  GLOBALS[] within other function: Hello
  foo within other function :

Apperently (in php3.0.3 only?) the variables created via $GLOBALS are
only available in 'global' space and not in the function where it is added 
to the globals. Even in another function it is not available.
Now that explains why I am not able to see a variable like temp_c in the 
phpweather script. It is added to the globals in a function, and it is used 
in another. This is what I got in the script:

  "16880919 minutes ago, at 00:00 UTC, the wind was calm in Aalborg,
   Denmark. The temperature was degrees Celsius ( degrees Fahrenheit),
   and the pressure was hPa ( inHg). The relative humidity was %. The
   sky was clear."

I bet that all variables that are being used in this part of the script
don't exist (or cannot be seen) in the function that prints this out.

Checking on the php 
docu:(http://www.php.net/manual/en/language.variables.scope.php)
  "You may notice that this is a little bit different from the C
   language in that global variables in C are automatically available
   to functions unless specifically overridden by a local definition.
   This can cause some problems in that people may inadvertently change
   a global variable. In PHP global variables must be declared global
   inside a function if they are going to be used in that function."

The only thing we have to do is making the $GLOBALS[$key] variables that are 
created in the extract() function available in the other functions. How can 
we do that (I'm a newbie to php)?

Yep, I'm going to ask them to upgrade to php4 , lets see what they have to 
say....

Thanks again for your help!
