Doc #68961 [NEW]: PDO::rollBack(): Unclear sentence on autocommit mode

From: chealer at gmail dot com Operating system: PHP version: Irrelevant Package: Documentation problem Bug Type: Documentation Problem Bug description:PDO::rollBack(): Unclear sentence on autocommit mode Description: ------------ --- From manual page: http://www.php.net/pdo.rollback --- The second paragraph reads: If the database was set to autocommit mode, this function will restore autocommit mode after it has rolled back the transaction. I am not knowledgeable on transactions and PDO autocommit mode, but I cannot make sense of that. If the database is in autocommit mode, how can the transaction be rolled back? Or in other words, which transaction would be rolled back? -- Edit bug report at https://bugs.php.net/bug.php?id=68961&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=68961&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=68961&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=68961&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=68961&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=68961&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=68961&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=68961&r=needscript Try newer version: https://bugs.php.net/fix.php?id=68961&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=68961&r=support Expected behavior: https://bugs.php.net/fix.php?id=68961&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=68961&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=68961&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=68961&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=68961&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=68961&r=dst IIS Stability: https://bugs.php.net/fix.php?id=68961&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=68961&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=68961&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=68961&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=68961&r=mysqlcfg
