OK - but you have told them to upgrade, haven't you?

I see - the manual explains that they were added in PHP version 3.0.7
and 3.0.6, respectively.

Instead of down-tuning, you could implement the two missing functions
yourself:

function extract($array) {

  while (list($key, $val) = each($array)) {
    $GLOBALS[$key] = $val;
  }

}

function str_replace($search, $replace, $subject) {

  $search_length = strlen($search);
  $replace_length = strlen($replace);
  $i = 0;
  while ($i < strlen($subject)) {
    if ($search == substr($subject, $i, $search_length)) {
      $subject = substr($subject, 0, $i) . $replace .
        substr($subject, $i+$search_length);
      $i += $replace_length;
    } else {
      $i += 1;
    }
  }
  return $subject;

}

I don't know if these functions work in PHP3, but I've tried to
restrict myself to functions that existed in PHP3, according to the
manual.

If the work, then I'll put them into two files, extract.php and
str_replace.php and include them in the tarball, so that people who
lack them can include the files before including the other PHP Weather
files. How does that idea sound?
