$_SERVER script not working?

npedrini

Hello. I'm very excited about learning php, but i have encountered a curious issue that i was hoping to get some assistance on.

Basically, it seems most statements are parsed fine except for the $_SERVER["HTTP_USER_AGENT"];

..HERE IS THE SIMPLE CODE:

But upon viewing http://mimesisinteractive.com/dev/server.php i get a blank page.

Any insight on what might be the problem?

Thanks for pointing me in a direction...

Your version of PHP (4.0.5) doesn't support the superglobal $_SERVER.

You'll need to use $HTTP_SERVER_VARS instead

<?php echo $HTTP_SERVER_VARS["HTTP_USER_AGENT"]; ?>

Or, you can upgrade to 4.2.x
But, if you do, the current versions of PHP have the register_globals defaulted to off. Meaning, you'll have to use your superglobals for all your exteranl variables (ie GET and POST)

😕 Curious.

When I go look at your page I see all of the code, including the PHP code.
So, the PHP page isn't being processed.

First, try and retype everything without copying from a web site.
I've sometimes suffered a problem with cut 'n paste w/ code.
Next make sure and remore the: ÿ<thorn>
from your page.

Thats strange, becuase all i see is a blank screen. I am at a University working, so i'm thinking that might have something to do with how pages are displayed and such. Maybe not the best place to experiment with server-side scripting?

I uploaded some stuff to a different account that uses 4.2.3, and it seems to have resolved a similar issue I was having with passing form variables to php. I am going to ask that a newer version be used on my primary hosting account.

BTW...can the php parser be run locally, i.e. from my cgi-bin or a location in my directory vs. the parent server?

thanks.

I don't know if you can use it locally.
I would imagine you could if you used a URL like:
localhost/test.php
but you would have to be on the machine that has the PHP module installed.

But I don't know for sure.
You can test pages locally with ColdFusion (when you are on that machine)
so i'd imagine its somehow possible with php
You'd just have to "trick" the PHP parser.

You might want to start anew thread asking 🙂

I do all my PHP testing from a remote server.
It's tedious to always havce to load pages
but I don't just do PHP development so the flexiblity is nice
And my machine doesn't have a web server on it.

BTW, you might want to contact the University's SysAdmin and let him know that his/her PHP Parser is acting a little strange.
Your test page works like a charm,
so i don't know what the problem could be?
