你如何强制PDOexception记录错误？ （PHP）

Question

I want to log database errors using PDO, but I do not want to have to repeatedly add logging to my catch blocks. Is there a way to force logging a PDOException?

Or would I have to create a class that extends PDO, then create a class that extends PDOExceptions and use them instead. Like the following:

try {
  $dbconn = new logPDO ( ... );
  //...
} catch (LogException $e ) {
  //..
}

I'd like to avoid creating new classes just to work around this. It seems strange that I can't log a PDOException.

Answer 1

The easiest thing would be to create a function that takes PDOException and did the logging logic.

function logPdo(PDOException $e) {
  // log stuff w/ the exception instance..
}

That could be a static method on a class too. If you wanted a more OO solution though, subclassing PDO and having it catch PDOException then throw a subclass or custom Exception class that has a log method or similar, that is a sound approach.
