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

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

switch ($t) {
case 'C':
echo $charcoal;
break;
case 'O':
echo $oil;
break;
case 'A':
echo $acrylic;
break;
}
}

ps. To OP. You can put all strings in file "lang.{$lang}.inc.php" in an
array and access it like this. If you do it like this you don't have to
change the function technique($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}.inc.php";
if ( file_exists($incFile) )
include ($incFile);
else
return; // or any other action



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

if (array_key_exists($t, $strings))
echo $strings[$t];

}
