mysql_driver->escape_str($str)

On my system this function pukes with a warning that mysql_real_escape_str was expecting a resource identifier but received a boolean when $str is ‘’.

I assume this is a PHP bug rather than a CI bug. But perhaps this could be smoothed by checking for an empty string in which case escaping would not be required. I’m running 5.1.6 on OSX Tiger.

Just letting you know ...

False alarm. Sorry!

The reason for these errors was related to the changes in PHP5 where variables get destroyed before the write/close handlers of a session handler are called. My session handler was using a the default database class referenced in the global CI object, whose connection was already closed when the write handler was firing. Boy oh boy - why in the world did Zend change that?

I think it was a conspiracy by the Zend framework people to make it look like CI had bugs… those rascals…

Thanks for updating your thread.  I was going to quickly try to recreate the problem myself, you probably just saved me an hour.
