Verständnisfrage global

[Jörg]

Sollte dann so was hier funktionieren?

  session_start();  
  if (empty($_SESSION['dirlist_o']) || empty($_SESSION['$_dirlist_t']) || empty($_SESSION['$_dirlist_r'])) {  
    $_dirlist_o = scan_dir ($original_dir);  
    $_dirlist_t = scan_dir ($thumbnail_dir);  
    $_SESSION['dirlist_o'] = $_dirlist_o;  
    $_SESSION['dirlist_t'] = $_dirlist_t;  
  
    if ($cookie == 'on') {  
      $_dirlist_r = $_dirlist_t;  
      $_SESSION['dirlist_r'] = $_dirlist_r;  
    }  
    else {  
      $_dirlist_r = scan_dir ($resized_dir);  
      $_SESSION['dirlist_r'] = $_dirlist_r;  
    }  
  }  
  else {  
    $_dirlist_o = $_SESSION['dirlist_o'];  
    $_dirlist_t = $_SESSION['dirlist_t'];  
    $_dirlist_r = $_SESSION['dirlist_r'];  
  }

Allerdings erstellt die Funktion "scan_dir" ein Multi.-Array.

Kann ich das da einfach so reinpacken?
