[wp-hackers] PHP5.3 and mysqlnd

[Jacob Santos]

Just a note for those testing WordPress using PHP 5.3 and using the 
mysqlnd driver for either mysql or mysqli.

You will need to make sure that your authentication for your connection 
username and password is using the 4.1+ or you won't be able to connect. 
Just had this happen to me. Just wanted to let everyone know in case 
they decided to use those in combination.

As an aside, WordPress does not pass certain E_DEPRECATED checks, so you 
may want to turn error_reporting off, unless you are testing. Also, 
since WordPress still supports PHP4, there won't be any fixes for the 
errors, or at least until WordPress sets the requirements to PHP5+.
