Including a file is so easy and takes so little time I wonder how this could be a problem.Good question, glad you asked. I have a header on all my pages. The header is HTML and containsimages. So of course I do an include("header.html") on all my pages ...The header is about 20K, having PHP read 20k off the disk everytime a user visits my page seemed inneficient. So I was trying to find a way to get PHP to cache the file in memory so it wouldn't have to read it off disk all the time ... I have lots of bandwidth but not enough money to pay for a proper SCSI/RAID disk set. All I have is a poor 7,2000 IDE HD. So the less disk seeks thebetter :) Jc If you are running under Linux.. load it up with RAM... the OS will hold any recent disk reads in cache... particularly a simple html document with a few locally held images. I've watched disk access on some of my boxes, some sites serving 1gig per day, and the disk just barely blips along... most being served from cache. Linux rules!
