Hi Ethan,

Is there a reason you're using shell commands to achieve the following:

<?php

     $path = '/var/www/orders.txt';
     if( !file_exists( $path ) )
     {
         if( !touch( $path ) )
         {
             echo 'Failed to touch file into existence: '.$path."\n";
         }
         else
         {
             if( !chmod( $path, 0766 ) )
             {
                 echo 'Failed to update file permissions: '.$path."\n";
             }
         }
     }

?>

Also, why are you setting the executable bit on a text file? :)

Cheers,
Rob.
