php or flash adding extra characters to txt file

[dave mccourt]

hi

i've set up a simple content management system using php. the cms flash movie reads and can write to a txt file using php. the problem is when the file is read (back into flash) and written a few times, extra empty or invisible characters apeear at the end of the txt file.

i have 2 php scripts that are used by the flash cms movie.

getfile.php reads the txt file into flash for editing:

<?
// Attempt to open file for reading
$file = @fopen($filename, "r");

// If the file was opened successfully...
if ($file) {

print "&status=$filename opened successfully!\n";

$output = fread($file, 11000);

print "&output=" . urlencode($output);

} else {

// Otherwise output failure message
print "&status=File not opened!\n";
}
?>

writefile.php writes the amended text to the txt file:

<?
urlencode($output);
$new = stripslashes($output);

// Attempt to open file for writing
$writable = @fopen($filename, "w+");

// If the file was opened successfully...
if ($writable) {

//write to file
fwrite($writable, $new);
fclose($writable);

print "&status=The file, $filename was updated successfully.";

} else {

// Otherwise output failure message
print "&status=File not updated to. Please click the back button to try again.\n";
}
?>

anyone know why this is?

many thanks
