cannot access inc files from a function

[bettina]

I have the following piece of code (symplified)

require("lang.{ $lang}.inc.php" ); // I include the inc. files
....
function decodify($techn ique) { // functions that give me back the
value in inc.file
switch ($technique) {
case 'C':
echo $charcoal;
break;
case 'O':
echo $oil;
break;
case 'A':
echo $acrylic;
break;
}
}
.....
Somewhere I call the function ....decodify($m yTechnique)

But it doen't print the content from $charcoal, $oil or, etc.
Do I have to declare the function global or something like that. In
that case, how should I do it??
Many thanks. Bettina

Hallo Bettina,

What is the exact name of the file you are trying to include. Your construct
is very weird, if the file is "lang.EN.inc.ph p" for example, try:

require("lang.$ lang.inc.php");

Also, could you post the code of that included file so we can see if the
values are really there.

Hope this helps,

You cannot access a variable that is outside of a function unless you
write global $var; inside the function. The other way is to include the
lang file inside the function.

Hi DXTrim,

the values are really there since I use the references outside the
function and it work ok. I think it has something to do with what says
Giannis regarding the global variable. I'll try that. Thank you.

How should I define the global variable inside this function? What must
be global is the lang.{$lang}.in c.php so that it can be read inside the
function, isn't it?. I tried including the lang file in the function
but I receive an error.

require("lang.{ $lang}.inc.php" );
function technique($t) {
switch ($t) {
case 'C':
echo $charcoal;
break;
case 'O':
echo $oil;
break;
case 'A':
echo $acrylic;
break;
}
}

$charcoal is local to your function. You can do it in two ways..

1.
function technique($t) {
global $charcoal;

switch ($t) {
case 'C':
echo $charcoal;

2.
function technique($t) {
switch ($t) {
case 'C':
echo $GLOBAL['charcoal'];

<? technique($myTe chnik ?>

function technique($t) {
global $lang; // here we are using the global var $lang
$incFile = "lang.{$lang}.i nc.php";

if ( file_exists($in cFile) )
include ($incFile);
else
return;

switch ($t) {

case 'A':

break;
}
}

ps. To OP. You can put all strings in file "lang.{$lang}.i nc.php" in an
array and access it like this. If you do it like this you don't have to
change the function technique($t) every time you put a new var in lang file.

// vars file
$strings = array (
"C" => "charcoal",
"O" => "oil",
"A" => "acrylic"
);
// index ? file
$incFile = "lang.{$lang}.i nc.php";
if ( file_exists($in cFile) )
include ($incFile);
else
return; // or any other action

// functions file
function technique($t) {
global $strings;

if (array_key_exis ts($t, $strings))
echo $strings[$t];

}

[bettina]

Thank you, the first option works ok!

[bettina]

Hallo Giannis, that of putting everything in my lang file so that I
don't have to change the function every time I add a new variable works
fine! Thank you for the tip!

Do I have to declare the function global or something like that. In
that case, how should I do it??
Many thanks. Bettina

to combine some of the ideas in this thread...
replace the whole case block with:

echo $GLOBAL[array('C'=>'cha rcoal','O'=>'oi l','A'=>'acryli c')[$technique]];
Bye.
