403 Forbidden chmod uploaded files

Just a trick,

If you upload a file through a PHP file ie. this way :

 
@unlink($file);

  if (is_uploaded_file($_FILES['photo']['tmp_name']))
  {
    rename($_FILES['photo']['tmp_name'], $file);

    chmod($file,0755);
  }


Note the PHP function chmod that changes the rights (Linux) for the file. --> 0755 is the correct mode, 755 will set wrong rights. You don't even have to use the system() function. It may help on certain servers (ie. Gentoo)

Also look at the php.ini file, the safe_mode options.

PHP chmod function :


<?php
chmod($file, 755);  // notation décimale : incorrect
chmod($file, "u+rwx,go+rx"); // chaîne : incorrect
chmod($file, 0755);  // notation octale : valeur du mode correcte
?>



<?php
// Lecture et écriture pour le propriétaire, rien pour le reste
chmod($file, 0600);

// Lecture et écriture pour le propriétaire, lecture pour le reste
chmod($file, 0644);

// Tout pour le propriétaire, lecture et exécution pour le reste
chmod($file, 0755);

// Tout pour le propriétaire, lecture exécution pour le groupe, rien pour le reste
chmod($file, 0750);
?>
