the constant CR_CONNECTION_ERROR is not defined.

this works:
if (mysql_errno() == 2002) { blah }

but this does not:
if (mysql_errno() == CR_CONNECTION_ERROR) { blah }

Aha I understand, sry for the confusion.

From this page (see below) there is a "see also" link which points to those constants.

I realize now that the link goes to the MySQL site however I did not realize this when I first met this problem.

Maybe a little note can be added besides this link, something like:

"Note: Make sure you use the actual error code integers not the constants because the constants listed in this document is not defined in PHP's MySQL-library."
