php - List Dir not functioning as expected -

i have used usercake make login system, altering suit needs.

originally list dir setup on page show of "help files" within specific folder. worked fine not secure , view. have changed security having few problems code:

//links logged in user if(isuserloggedin()) {       //links permission level 3 (bof)     if ($loggedinuser->checkpermission(array(3))){      if ($handle = opendir('cd500/')) {     while (false !== ($file = readdir($handle)))         {             if ($file != '.' && $file != '..'){              $thelist .= '<a href="/cd500/'.$file.'' target='_blank' >'.$file.'</a></br>';             }         }      closedir($handle);     }       echo "     <div id='output'>     list of files:</div>     <div id='list'>     $thelist  

this whole completed package. wondering if simple many if statements?

it not parse, html loads , images appear never materializes.

i set up:

//links logged in user if(isuserloggedin()) {       //links permission level 3 (bof)     if ($loggedinuser->checkpermission(array(3))){       foreach(glob('./bof/*.*') $filename){       echo $filename ;      }    }  

my problem whilst works, make presentable have far failed do.

i ideally fix first solution, if not how can style second?

this line

$thelist .= '<a href="/cd500/'.$file.'' target='_blank' >'.$file.'</a></br>'; 

should be

$thelist .= '<a href="/cd500/'.$file.'" target="_blank" >'.$file.'</a></br>';
