PRINT getenv(REMOTE_ADDR);???

[Anon]

Why do I not get the remote address consistently??

I get it in this code

<?php

PRINT getenv(REMOTE_ADDR);
PRINT getenv(REMOTE_PORT);
PRINT getenv(HTTP_USER_AGENT);
PRINT getenv(HTTP_REFERER);
PRINT getenv(HTTP_HOST);
PRINT getenv(HTTP_SERVER_VARS);
?>

i do not get it in this code

$ip=getenv(REMOTE_ADDR); 
PRINT getenv(REMOTE_ADDR);
print "<input type=\"hidden\" name=\"usrip\" value=\"$ip\">\n";
$agt=getenv(HTTP_USER_AGENT); 
print "<input type=\"hidden\" name=\"usragt\" value=\"$agt\">\n";
$hst=getenv(HTTP_HOST);
print "<input type=\"hidden\" name=\"usrhst\" value=\"$hst\">\n";

any clues id appreciate it - its beyond me - thansk.

I would guess it has to do with your webserver. It has to pass all the VARs into PHP in order for them to be set.
