Shopping Cart Order Export Enhancement

We have Opencart Shopping Cart system and use a custom ORDER EXPORT program. We need an enhancement to the ORDER EXPORT program: The program adds orders to a [url removed, login to view] file.

1. Right now the program writes the orders to orders.csv. Edit it to write the orders to [url removed, login to view] and also write the orders to [url removed, login to view] as well, which we can clear manually as it grows.

2. To prevent concurrent writing to a file and the file getting corrupted, we need a file locking mechanism. i.e. if [url removed, login to view] file is opened for writing, then if an order comes from another browser, then lock the file ([url removed, login to view]), till the first write operation is completed, then unlock it for the second process.

3. Set cron job once an hour 50 minute) Lock [url removed, login to view] file and copy (NOT append) [url removed, login to view] to orders.csv. Clear out [url removed, login to view] and unlock
