Here's the code I'm using:

PHP Code:

<?php
$filename = 'visitors.txt';
$screenname = $_GET ['screenname'];
if (is_writable($filename)) {
   if (!$handle = fopen($filename, 'a')) {
         echo "Cannot open file ($filename)";
         exit;
   }
   if (fwrite($handle, $screenname) === FALSE) {
       echo "Cannot write to file ($filename)";
       exit;
   }
   echo "Success, wrote ($screenname) to file ($filename)";
   fclose($handle);
} else {
   echo "The file $filename is not writable";
}
?>

But the problem is I need to have a line break after every screenname that get's put in the file. Any help?

Change the following:

PHP Code:

// Find...
$screenname = $_GET ['screenname'];
 
// Change to...
$screenname = $_GET['screenname'] . "\n"; 


This will append a newline after each entry, ready with a newline for the next time.
