Re: [PHP] Efficieny: Include vs Array vs Function

Thanks for the reply. In my case there aren't many external files associated with the script. 1 css file per site and no images except on a few very specific pages. Adding images does not negate the shaved microseconds. I see what you mean, but it doesn't literally negate the saved load. Th

[PHP] Does using msql_select_db excessively burn resources?

I plan to have my sites using several databases, but there is a common database they must all use. Obviously I'll have to use "mysql_select_db" each time I change the database I wish to use. Does this simply select the database and hold it as a variable until a query is made, or does it load i
