This is the way i would do it: (Avoiding searching latest 5 message in a
file etc)
Assuming you have already x posts in a file:
allposts.txt
Store the last 5 most recent posts in a file:
x+4.txt x+3.txt x+2.txt x+1.txt x.txt
(Say you already 10 posts, the files would be 14.txt, 13.txt, ...
10.txt)
Now each time a post is added, append it to allposts.txt and put it in a
file called x+6.txt. Remove the file x.txt
Next time a post is added, append it to allposts.txt and put it in a
file called x+7.txt. Remove the file x+1.txt
(In general: remove the x-5th file)
To show the most recent posts, instead of searching in allposts.txt just
display the 5 txt files ;)
