I'm sorry, I feel dense coming to the list for this, because I'm SURE I've read about this in the PHP or Mysql docs, but I can't seem to locate where.
Let's say users submit a form which is processed by a PHP page which performs a number of MySQL INSERT, UPDATE, and/or DELETE commands. .
What happens if the user hits "Stop" or "Refresh" in their browser before the transaction is complete - is there a possibility that only some of the MySQL commands will complete? Not a problem if the services are all running well, but I'm thinking if things are getting thrashed on the server for whatever reason, it might take several seconds to complete the various SQL commands, also increasing the likelihood of the user getting bored enough to start playing "bull in a browser shop".
And since MySQL has no rollback feature that I'm aware of, how would you best handle this dangerous potentiality? Suggestions? A humble request: Responses which begin with: "Don't use MySQL", please include a good affordable alternative?
