Alleged Re-Declaration of function in PHP -


i'm getting php fatal error:

fatal error: cannot redeclare getstring() (previously declared in path/src/scripts/php/functions.php:66) in path/src/scripts/php/functions.php on line 111

these files included:

  1. index.php "is" page
  2. functions.php called index.php via require_once. includes functions , stuff
  3. error.php called functions.php when error in given function appears. error.php calls functions.php, via require_once, in case should not call functions.php second time

i know error means. function declared once. also, error occurs when call in function within functions.php.

here function:

function getstring($key, $lang) { if (!is_string($key) || !is_string($lang)) {     $fehlercode = "stringnostring";     require_once ("path/src/logs/error.php");     exit; } $urkey = $key; $key = (string) $key; if (strlen($key) < 5) {     switch (strlen($key)) {         case 4:             $key = "0".$key;             break;         case 3:             $key = "00".$key;             break;         case 2:             $key = "000".$key;             break;         case 1:             $key = "0000".$key;             break;         default:             break;     } } global $de_array, $en_array;  if ($lang == "en") {     if (array_key_exists($key, $en_array)) {         return $en_array[$key];     } else {         $fehlercode = "nostringon(".$key."en)";         require_once ("path/src/logs/error.php");         exit;     } } else {     if (array_key_exists($key, $de_array)) {         return $de_array[$key];     } else {         $fehlercode = "nostringon(".$key."de)";         require_once ("path/src/logs/error.php");         exit;     } } }

it works, when call in index.php this:

<? echo getstring("00004", $preflang); ?>

but doesn't work, when call function within function in functions.php this:

$faqs = '<div class="zweispaltigez"><div class="left"><h3>'.getstring("00087", $preflang).'</h3><ol>'.$questions.'</ol></div><div class="right"><h3>'.getstring("00088", $preflang).'</h3>'.$answers.'</div></div>'; return $faqs;

there nothing wrong function calling getstring(), because when replace hardcoded text, works.

edit

i "solved" fatal error removing code calls error.php , exits. however, now, getstring() function still doesn't function properly. calling directly index.php (like above) works fine, calling within function leads no output @ all.
