Req #74957 [NEW]: Introduce interfaces PDOInterface and PDOStatementInterface

From: aljosha dot papsch at vinexus dot eu Operating system: PHP version: Irrelevant Package: PDO Core Bug Type: Feature/Change Request Bug description:Introduce interfaces PDOInterface and PDOStatementInterface Description: ------------ Classes PDO and PDOStatement do not implement any interface, making it harder to add custom behaviour. For example, PDO does not handle reconnecting to database, which is an issue especially in long running processes. The best shot at implementing this feature is creating custom behaviour classes with the same methods as PDO/PDOStatement (most of it should just be adapter stuff). Unfortunately the custom behaviour class cannot be used in functions which have PDO/PDOStatement typehint, making them useless. If PDO and PDOStatement implemented interfaces, it would be possible for the custom behaviour classes to implement those interfaces as well, making them interchangeable. No changes needed in callers of PDO/PDOStatement. -- Edit bug report at https://bugs.php.net/bug.php?id=74957&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=74957&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=74957&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=74957&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=74957&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=74957&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=74957&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=74957&r=needscript Try newer version: https://bugs.php.net/fix.php?id=74957&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=74957&r=support Expected behavior: https://bugs.php.net/fix.php?id=74957&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=74957&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=74957&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=74957&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=74957&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=74957&r=dst IIS Stability: https://bugs.php.net/fix.php?id=74957&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=74957&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=74957&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=74957&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=74957&r=mysqlcfg
