note 94316 modified in function.mysql-connect by danbrown

On Windows Vista or above, an entry in the Windows/System32/drivers/etc/hosts file causes mysql_connect() connections to "localhost" to timeout and never connect. This happens on php 5.3 and above since it now uses mysql native driver which has changed it connection behavior compared to libmysql.dll in previous versions. It is not a PHP bug, but definitely a configuration issue for users on new windows systems. To get around this, you must remove the entry like this: ::1 localhost and make sure you still have: 127.0.0.1 localhost Also, you could change the code to connect to the ip instead, but that is inconvenient if you have many web sites. This issue occurs on Windows Vista, Windows 7 and Windows Server 2008. --was-- On Windows Vista or above, an entry in the Windows/System32/drivers/etc/hosts file causes mysql_connect() connections to "localhost" to timeout and never connect.

I lost MANY hours on this small change and found the answer in a closed PHP report that was kind of ignored. PHP Team: Perhaps this should be in the windows installation manual?
