What is the difference between mysqli_begin_transaction () and mysqli_autocommit

问题

Does mysqli_begin_transaction() achieve the same functionality as mysqli_autocommit () ?

回答1:

• mysqli_autocommit() sets autocommit mode permanently. It means that if you set it to 0 and then commit a transaction, the mode will remain 0.
• mysqli_begin_transaction() begins a single transaction. It means after commit the mode reverts to its previous state.
  besides, it allows you to fine tune a transaction, starting it in one of the following modes:
  • MYSQLI_TRANS_START_READ_ONLY.
  • MYSQLI_TRANS_START_READ_WRITE
  • MYSQLI_TRANS_START_WITH_CONSISTENT_SNAPSHOT
    You can read on the modes in mysql documentation, https://dev.mysql.com/doc/refman/5.7/en/commit.html
