creating plugins, question on multiple instances of the database connections

Hi there, I have a question when creating plugins, if I have several plugins all using different database scripts (perhaps a login script, a script for a dynamic menu etc) each of these seperate plugin files will obviously have a require_once database connection script.

Therefore that would then suggest that the final page will have multiple instances of the "require_once database connection? also there would be multiple instances of @session_start...all due to created the code in seperate files.

So my question is, will this cause server problems in terms of speed or functionality to some extent?

No, this will not create a problem on the server.


the point of using require_once to include a file is to prevent it from being included multiple times if there are multiple instances of the require_once line. The include file can be called as many times as you like, but the php server will only access it the one time due to using require_once.

the session_start call can also be done multiple times without a consequence.

Thankyou...I do feel stupid since what you said made complete sense (when thinking of the phrase "required_once" - I bow my head in shame. Thanks again :)
