Question about performance

Hello All! I'm currently doing some writing and I'm wondering about a potential performance issue. My question is about assigning some array variables. I have a script that works as a navigation sidebar. When you are at a certain area, say for instance Health Department, an additional set of links is parsed from an array of links for the Health Department. My question is, when I get a number of areas (say upwards of 20 or 30) should I assign ALL of the arrays in one include file that EVERY page then uses OR should I have separate includes for each area that defines the links array only for that area? You can see it kind of in action at www.lcounty.com Thanks, John --------------------- John Asendorf - jasendorf@lcounty.com Web Applications Developer Licking County, Ohio, USA
