get_env not working

raspberryh

Hi,
I am using PHP 5.1.2 and the getenv() function is not working - it returns an empty string. Does anyone know if there is some kind of setting in the setup of PHP that would control this? We just got the site switched to a new server so I don't know if maybe there's a setting that's different or something. Oh yeah and I'm viewing the site with Firefox version 1.0.7 but it does the same thing in IE as well.
The PHP setup info is here: http://allstarfg.com/phpinfo.php
Thanks,
Heather

I'm having exactly the same problem you discribed here and wondered if you had found the solution.

cac - can you show us the code you tried?

I was trying to do something like this:

<?php
$ip = getenv("REMOTE_ADDR") ;
Echo "Your IP is " . $ip;
?>

which gave me a blank where the IP number should be. This morning I discovered that I can succesfully do this:

<?php
$ip=$_SERVER['REMOTE_ADDR'];
echo "Your IP is $ip";
?>

Which gets me through my problem, but I can't help wondering why I had a problem.

I have no idea... but using the $_SERVER superglobal is definitely the more preferred/common way.
