strtr VS CI bug? result parse error

[eluser]metaltapimenye[/eluser]
hi guys.. i think i found kind of bug while migrating old system on my office.
conditions:
fetching array trough native while() => mysql_fetch_assoc().

controler:

Code:

<?php
class Welcome extends Controller {

    function Welcome(){
          parent::Controller();
        }
        function index(){
        $this->load->view('old/something');
    }
        function bug(){
          $this->load->view('old/bug');
        }
}

view/old/bug.php

Code:

<?php
$s=mysql_query('select * from promotion where 1 /*promoend >= CURDATE()*/ order by promoid desc');
$c=mysql_num_rows($s);
$d=date('Ymd');
    
while($r=mysql_fetch_assoc($s)){
  ##bug(?) notice: start
  echo $c=(strtr($r['promoend'],array(" "=>"","-"=>"",":"=>""))>$d)?'#caffca':'#e9e9e9';
  ##notice:end
}?>

related route:

Code:

$route['^(?!test).*'] = "welcome/$0";

url hit: http://localhost/CI_Dir/bug

result:
Parse error: parse error in C:\wamp\www\CI_Dir\system\application\views\old\bug.php on line (line_num)

note:i use index.php cleanup .htaccess

its running well when i replace and reassign the variable [notice] part to..

Code:

$new_var=strtr($r['promoend'],array(" "=>"","-"=>"",":"=>""));
echo $c=($new_var > $d)?'#caffca':'#e9e9e9';

thx
