Since I'm the one who started this, let me explain why I'm doing what I am.
The code I'm writing is one-time use code, and I need ease-of-coding more than I need efficient use of resources. The code is devilishly complex as it is, and having to deal with selecting the db every two lines would just make it that much more complex.

It's not a silly behaviour. Database connections are a very limited resource, much more so than open files, and time after time we saw code that would open up multiple identical connections for no reason whatsoever. This is especially true of large apps that are able to swallow other apps. Like PHP-Nuke with various plug-in modules. If you patch 3 or 4 different things together that all talk to a DB on localhost, you do not need to go through the code and unify the database handling to avoid having 4 separate connections per request. PHP automatically optimizes that for you. Opening a new connection is also extremely expensive, much more so than a simple db switch call on an existing one. -Rasmus On Mon, 22 Apr 2002, Daniel Lorch wrote: > Hi, > > > No, it doesn't satisfy me at all.
