header + global $var in function problem

[gregory]

Hi,

I'm trying to use Coppermine Gallery on my website with my header.inc.php & footer.inc.php.
In "header.inc.php" file I include the file "function.inc.php". In "function.inc.php" I have a code below (just example):

Code Select Expand

$var99 = 50;

echo "1." . $var99;

function getVar()
{
  global $var99;

  echo "2." $var99;
}The result is:

Code Select Expand

1. 50
2.
What is the problem? All the variables are work but not inside the function when I define them through "global".
I'm testing this problem on the page: http://domain.com/gallery/thumbnails.php?album=1

Please help.

It's not in scope. Your code should be like this:

Code Select Expand


<?php

global $var99;

$var99 = 50;

echo "1." . $var99;

function getVar()
{
  global $var99;

  echo "2." . $var99;
}

getVar();

I know. It's just an example. Sure I call this function. That why I wrote "2. "

[Nibbler]

Did you try the code I posted?

[gregory]

Oh, I've missed the first "global".
Thank you very much! Everything is working.
Can you please describe me what was the problem? Is this header inside of another function or what?

[gregory]

I've found another problem.

"global $var;" is working but "global $var1, $var2" shows me only $var1.

[gregory]

I mean this global variables are working inside the function now but don't work outside this function as earlier)))

The code is included from within a function in Coppermine. Not sure what your issue with multiple globals is, works for me.

Code Select Expand


<?php

global $var1, $var2;

$var1 = 50;
$var2 = 60;

echo "1. " . $var1 . '.' . $var2;

function getVar()
{
  global $var1, $var2;

  echo "2. " . $var1 . '.' . $var2;
}

getVar();
