If its working, it much further ahead yeah.
This won't work, at least not the way it's supposed to:
if ($sStatus == 01). It *will* work because of PHP's datatype weakness, but it won't work logically since you are comparing a string '01' to octal 01. With the datatype weakness this compares 1 to 1. I'd suggest keeping them as string comparisons though.
I'd also still use the is_file check, but provide a hard coded alternative path for just in case it cannot find the file you have specified.
As of PHP 5.5, the MySQL library has been officially deprecated. It is recommended to move to either MySQLi or PDO libraries for your mysql connectivity. See here for help choosing which interface you prefer: http://php.net/manual/en/mysqlinfo.api.choosing.php
