$_SERVER not working

[Puneet]

I really loosing sleep over this one. I have php 4.4 running on Apache
2.... php works fine. phpinfo() retuns everything as it should..
However when I try to print anything using $_SERVER e.g $_SERVER
['HTTP_HOST']... it returns nothing. Then I realized that even $_GET
and $_POST are not working. All the uper globals are not working. They
just come back with e.g Array ['HTTP_HOST']... Can any body help?

Sound like you need some curly brackets:

echo "{$_SERVER['HTTP_HOST']}";

Re: $_SERVER not working

Nope.. If i use your code.. then I am getting this..

PHP Notice: Undefined index: HTTP_HOST in C:\Program Files\Apache
Group\Apache2\h tdocs\_debug_tm p.php on line 5

............... ............... ..............^
That a space between the SERVER and ['HTTP Oops, take it out.

Then it is (probably) not present in the http-request. Blame your
browser/proxy.

Perhaps you can use 'SERVER_NAME' instead.

Wouldn't work. When using an array inside an string, you will need the curly
brackets to tell PHP to use the index.

Since the index is not used, it just tells you that $_SERVER is an array.

Re: $_SERVER not working

Thanx Bent... That helped..
I rewrote the code as :-
print "Host port is :". $_SERVER ['SERVER_PORT'] ;

and it worked...

There has to be a space between SERVER and [.. otherwise PHP throws an
exception.

Not on any system I've ever used. The space is optional.

However - if you don't have the curly braces around it, I can see where PHP
might get confused.
