Asunto: [php] $_SELF[PHP_SELF] not working anymore
Importancia: Baja


Hi there!

I'm currently developing some pages where I use
$_SELF[PHP_SELF], always without any kind of problem
(until some days ago).

Some days ago, as I said, I formated my hard disk,
installed everything again and from that day on
$_SELF[PHP_SELF] stopped working, same goes for
$_SERVER[REQUEST_URI] or $_GET[location] (which are
the solution I tried to find, without success). The
page says:

Notice: Undefined index

(for $_GET) or it just says nothing (the other ones
above, no error reported, it just displays nothing).

Inside PHP.ini I have globals set to On, but if I set
them to Off nothing changes...

Can anyone help me? At PHP.net I saw "If PHP is
running as a command-line processor, this variable is
not available", but I am running it from a web page on
Windows 2000 + Xitami.

Thanks a lot for your help and sorry if I asked
something stupid, but I couldn't find any solution....

Kisses,
Maria

You should always quote your array keys (cept if all the keys are
numeric. Also when inside a string, enclose your variables with
{}.

$currentAddress="{$_SERVER['HTTP_HOST']}{$_SERVER['PHP_SELF']}";


php wont be so confused as what you're trying to do.

Hi there!

First, thanks for your reply...

I also tried with $_SERVER[PHP_SELF] alone (echo
"$_SERVER[PHP_SELF]"; or echo
"$_SERVER['PHP_SELF']";), and it doesn't work. I
personally don't think PHP is confused about what I'm
trying to do...

Thanks anyway.

Do you have any other idea? I already ran out of
them... :-(

Kisses,
Maria

Does the above not work?

What does "and it doesn't work" actually mean? There's no output? There's an
error message? The monitor explodes?

What version of PHP are you using? Have you turned on all error reporting? And
what does

print_r($_SERVER);

give you?

How about:

$currentAddress = $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'];

Huh?
I thought that the array key does not have to
be quoted if it's in a double-quoted string; here
is a program I made to test it:

1 <?php
2 // PHP 4.0.5
3 error_reporting(E_ALL);
4
5 define ('SIX', 6);
6 $arr[SIX] = 'six word';
7 // $arr['SIX'] = 'String of six';
8
9 // Generates an error; the key is assumed correctly to
10 // be a string
11 echo "<p>Show 1: $arr[SIX] (should show 'String of six')</p>\n";
12
13 // Performs okay; the key is assumed correctly to
14 // be a constant.
15 echo "<p>Show 2: {$arr[SIX]} (should show 'six word')</p>\n";
16
17 // There is no ambiguity between
18 // "$arr[<CONSTANT>]" and "$arr[<STRING>]"
19 // since $arr[<CONSTANT>] must be placed
20 // inside of braces {}
21 ?>

Depending upon which line is commented out (between
lines 6 and 7), either line 11 or line 15 will generate
an error.

If $arr[SIX] does not exist, PHP (4.0.5) does not assume
that the programmer means $arr['SIX'].

And if $arr['SIX'] does not exist, PHP does not assume
that the programmer means $arr[SIX]--no ambiguity.

If it is done in a quoted string, leaving the quotes
off the key is safe. However, because I'm using an
antiquated version of PHP, I don't know if the behavior
is different for newer versions of PHP. So, can anyone
tell me how later versions act wrt this?
