I'm currently working on a PHP project where I need to handle database transactions. While exploring the available functions, I came across the rollback() function in PHP. However, I'm a bit confused about its functionality and how to use it effectively in my code.
To provide some context, I'm building an e-commerce website where users can place orders. As part of the order processing, I want to ensure that the database updates related to inventory and order status are atomic - either all updates occur successfully or none at all. This is where transactions come into play.
I've been reading the PHP documentation, but I'm still unsure about how to incorporate the rollback() function into my code. Can anyone explain the purpose and usage of rollback() in PHP, particularly in the context of database transactions?
If possible, it would be great if you could also provide an example showing how to use rollback() in a simple database transaction scenario. I'm keen to understand how to use this function effectively to handle any potential errors during transaction processing.
Thank you so much for your help! I appreciate any assistance or insights you can provide.
