function in variable

[Narfotic]

Prolly an absolute newbie question, but how do I trigger a function as this one (which should take the name of a variable and then add "-en" to it):

function trans_var($var){
   $temp = explode(".",$var);
     $temp[count($temp)-2] .= "_en";
     print(implode(".",$temp));
 } 

in a variable like this one (replacing the 'message' with 'message_en')

<?php echo($news["message"]);?>

I allready tried some like this:

<?php print($news[trans_var('message')]);?>

but it just doesnt work

How can I do this?

fix your function to this:

function trans_var(&$var){
   $temp = explode(".",$var);
    $temp[count($temp)-2] .= "_en";
    return implode(".",$temp);
} 

and then you can do this:

print trans_var($news['message']);

a little tip i was given a while ago - try and avoid printing from functions, echo'ing is generally ok but either way i would avoid printing inside a function. store the values in a variable and return them as shown above... then print out the result of the function.
