Why isn't this global?

I feel as though your are getting confused....can we see the actual code where you are using this...

:o)

Ant

My actual code looks like this:

<?php

$bgcolor1 = "#000000";
$bgcolor2 = "#FFFF00";
$bgcolor3 = "#CCCC00";
$bgcolor4 = "#FFFF00";
$textcolor1 = "#FFFFFF";
$textcolor2 = "#FFFF00";
$bgimage1 = "themes/CCore/images/barra.gif";

function themeindex (...) {
    global $bgcolor1, $bgcolor2, $bgcolor3, $bgcolor4, $textcolor1, $textcolor2, $bgimage1;
    echo "$bgimage1";
...


and that last line echoes an empty string.

Replace

echo "$bgimage1";

with

echo $GLOBALS["bgimage1"];

and tell me if that makes any difference.

What parameters are you passing to the function?

Ant

Using $GLOBALS made no difference. None of the function parameters have the same variable name.

What about if you move $bgimage1 from the end to somewhere else in the global statement? Does it work then?

What version of PHP are you using? e.g. 4.0.5

Ant

Here's an odder bit: if I do the following:

$bgimage1 = "themes/CCore/images/barra.gif";
...
function themesidebox($title, $content) {
    global $bgcolor1, $bgcolor2, $bgcolor3, $bgcolor4, $textcolor1, $textcolor2, $bgimage1;
    echo "bgimage1=$bgimage1";
    $bgimage1 = "themes/CCore/images/barra.gif";

...then $bgimage1 appears blank when the echo is first displayed, but is correctly set by the next line and the echo displays the image URL every time thereafter.

It does seem like a bug....which is why I asked the last lot of questions that I did.....any response to them? :o)

Ant

To me it sounds like either that variable has been
reserved by PHP in some strange way or a plain bug.
I ran the following code on 2 machines:

<?php
$bgcolor1 = "#000000";
$bgcolor2 = "#FFFF00";
$bgcolor3 = "#CCCC00";
$bgcolor4 = "#FFFF00";
$textcolor1 = "#FFFFFF";
$textcolor2 = "#FFFF00";
$bgimage1 = "themes/CCore/images/barra.gif";
function themeindex () {
global $bgcolor1,$bgcolor2,$bgcolor3,$bgcolor4,$textcolor1,$textcolor2, $bgimage1;
echo $bgimage1."<br>".$bgcolor1;
}
themeindex();
echo phpinfo();
?>

..and the result as follows:

WIN PHP 4.0.5 (apache) OUTPUT:
themes/CCore/images/barra.gif
#000000

LINUX PHP 4.0.4pl1 OUTPUT:
themes/CCore/images/barra.gif
#000000

Why not just rename that bloody variable? :)
/Regards Spiffen.

I've renamed the variable once before ($bgbar1 to $bgimage1), with no change.

Not sure what version of PHP it is; I'm not running it on my own machine.

Have you tried moving it from the end of the list like I suggested and seeing if that makes any difference?

Ant

You'll see the PHP version if you echo phpinfo();
<?php
 echo phpinfo();
?>

Spiffen,

Just as a note, I never need to use echo for phpinfo().

If I do, I get an extra "1" at the bottom of the page (which I suppose represents True as the function worked OK!).

Of course. :-)  v.4.0.0, it sez

I agree with the previous comments that this sounds like an early PHP 4 bug.  

I have found it useful to sometime include the following snipit in my function to get "C" like globals.

     // import globals
     foreach (array_keys($GLOBALS) as $key)      {
          if(!isset(${$key})) global ${$key};
     }
