session problem

I am trying to open a named pipe and saving the file pointer using a session variable. However, while other session variable seem to be saved just fine, the session variable for the file pointer doesn't get saved.

<?php
if (($_SESSION['Pipe_open'] == 0 ))
{
  if  ( !( $_SESSION['Pipe_fp'] = fopen(\"/Users/administrator/Sites/maps/PipeFile\",\"w\") ) )
    echo \"ERROR :: Can't open PipeFile<br>\";
  else
    $_SESSION['Pipe_open'] = 1;  
}

$Pipe_fp_check = $_SESSION['Pipe_fp'];

if ( !($Pipe_fp_check) ) echo \"Error :: pipe not open<br>\";
?>

The first time around, the pipe gets opened and everything checks out fine. The next time around, it doesn't re-open the pipe, but the Pipe_fp session variable is not set anymore.

Can anyone help? Thanks a million

ok, I guess I can't assign file pointers to session variables... time to move on...

from the manual :
